lib: support overriding http\s.globalAgent
Overriding `require('http[s]').globalAgent` is now respected by
consequent requests.

In order to achieve that, the following changes were made:

1. Implmentation in `http`: `module.exports.globalAgent` is now defined
through `Object.defineProperty`. Its getter and setter return \ set
`require('_http_agent').globalAgent`.

2. Implementation in `https`: the https `globalAgent` is not the same
as `_http_agent`, and is defined in `https` module itself. Therefore,
the fix here was to simply use `module.exports.globalAgent` to support
mutation.

3. According tests were added for both `http` and `https`, where in
both we create a server, set the default agent to a newly created
instance and make a request to that server. We then assert that the
given instance was actually used by inspecting its sockets property.
