The default `--max_restarts` for `torch.distributed.run` was changed to `0` from `3` to make things backwards compatible with `torch.distributed.launch`. Since the default `--max_restarts` used to be greater than `0` we never documented passing `--max_restarts` explicitly in any of our example code.

Very crude first implementation of `torch.nanmean`. The current reduction kernels do not have good support for implementing nan* variants. Rather than implementing new kernels for each nan* operator, I will work on new reduction kernels with support for a `nan_policy` flag and then I will port `nanmean` to use that.

Summary:
Partially resolves https://github.com/pytorch/vision/issues/4281
In this PR we are proposing a new scheduler --SequentialLR-- which enables list of different schedulers called in different periods of the training process.
The main motivation of this scheduler is recently gained popularity of warming up phase in the training time. It has been shown that having a small steps in initial stages of training can help convergence procedure get faster.
With the help of SequentialLR we mainly enable to call a small constant (or linearly increasing) learning rate followed by actual target learning rate scheduler.
```PyThon
scheduler1 = ConstantLR(optimizer, factor=0.1, total_iters=2)
scheduler2 = ExponentialLR(optimizer, gamma=0.9)
scheduler = SequentialLR(optimizer, schedulers=[scheduler1, scheduler2], milestones=[5])
for epoch in range(100):
train(...)
validate(...)
scheduler.step()
```
which this code snippet will call `ConstantLR` in the first 5 epochs and will follow up with `ExponentialLR` in the following epochs.
This scheduler could be used to provide call of any group of schedulers next to each other. The main consideration we should make is every time we switch to a new scheduler we assume that new scheduler starts from the beginning- zeroth epoch.
We also add Chained Scheduler to `optim.rst` and `lr_scheduler.pyi` files here.

Summary:
Partially unblocks https://github.com/pytorch/vision/issues/4281
Previously we have added WarmUp Schedulers to PyTorch Core in the PR : https://github.com/pytorch/pytorch/pull/60836 which had two mode of execution - linear and constant depending on warming up function.
In this PR we are changing this interface to more direct form, as separating linear and constant modes to separate Schedulers. In particular
```Python
scheduler1 = WarmUpLR(optimizer, warmup_factor=0.1, warmup_iters=5, warmup_method="constant")
scheduler2 = WarmUpLR(optimizer, warmup_factor=0.1, warmup_iters=5, warmup_method="linear")
```
will look like
```Python
scheduler1 = ConstantLR(optimizer, warmup_factor=0.1, warmup_iters=5)
scheduler2 = LinearLR(optimizer, warmup_factor=0.1, warmup_iters=5)
```
correspondingly.

## Changes
- [x] Add `torch.concat` alias to `torch.cat`
- [x] Add OpInfo for `cat`/`concat`
- [x] Fix `test_out` skips (Use `at::native::resize_output` or `at::native::resize_output_check`)
- [x] `cat`/`concat`
- [x] `stack`
- [x] `hstack`
- [x] `dstack`
- [x] `vstack`/`row_stack`
- [x] Remove redundant tests for `cat`/`stack`
~I've not added `cat`/`concat` to OpInfo `op_db` yet, since cat is a little more tricky than other OpInfos (should have a lot of tests) and currently there are no OpInfos for that. I can try to add that in a subsequent PR or maybe here itself, whatever is suggested.~
**Edit**: cat/concat OpInfo has been added.
**Note**: I've added the named tensor support for `concat` alias as well, maybe that's out of spec in `array-api` but it is still useful for consistency in PyTorch.

Summary:
Implements an orthogonal / unitary parametrisation.
It does passes the tests and I have trained a couple models with this implementation, so I believe it should be somewhat correct. Now, the implementation is very subtle. I'm tagging nikitaved and IvanYashchuk as reviewers in case they have comments / they see some room for optimisation of the code, in particular of the `forward` function.

Summary:
This PR introduces a new `torchrun` entrypoint that simply "points" to `python -m torch.distributed.run`. It is shorter and less error-prone to type and gives a nicer syntax than a rather cryptic `python -m ...` command line. Along with the new entrypoint the documentation is also updated and places where `torch.distributed.run` are mentioned are replaced with `torchrun`.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/63910
Addresses the current issue that `init_method=tcp://` is not compatible with `torch.distributed.run` and `torch.distributed.launch`. When running with a training script that initializes the process group with `init_method=tcp://localhost:$port` as such:
```
$ python -u -m torch.distributed.run --max_restarts 0 --nproc_per_node 1 --nnodes 1 --master_addr $(hostname) --master_port 6000 ~/tmp/test.py
```
An `Address in use` error is raised since the training script tries to create a TCPStore on port 6000, which is already taken since the elastic agent is already running a TCPStore on that port.
For details see: https://github.com/pytorch/pytorch/issues/63874.
This change does a couple of things:
1. Adds `is_torchelastic_launched()` check function that users can use in the training scripts to see whether the script is launched via torchelastic.
1. Update the `torch.distributed` docs page to include the new `is_torchelastic_launched()` function.
1. Makes `init_method=tcp://` torchelastic compatible by modifying `_tcp_rendezvous_handler` in `torch.distributed.rendezvous` (this is NOT the elastic rendezvous, it is the old rendezvous module which is slotted for deprecation in future releases) to check `is_torchelastic_launched()` AND `torchelastic_use_agent_store()` and if so, only create TCPStore clients (no daemons, not even for rank 0).
1. Adds a bunch of unittests to cover the different code paths
NOTE: the issue mentions that we should fail-fast with an assertion on `init_method!=env://` when `is_torchelastic_launched()` is `True`. There are three registered init_methods in pytorch: env://, tcp://, file://. Since this diff makes tcp:// compatible with torchelastic and I've validated that file is compatible with torchelastic. There is no need to add assertions. I did update the docs to point out that env:// is the RECOMMENDED init_method. We should probably deprecate the other init_methods in the future but this is out of scope for this issue.
Test Plan: Unittests.
