Fix pushing large files over SCP

[Jakuje]

SUMMARY

The SCP is trying to read the whole file into memory and send it as a whole to the server. This is very prone to hit some memory limits of the machine with larger files.

This changes the implements similar approach to the get() operation as done in #621, including very similar test.

Fixes: #654

Looks like tests/unit/channel_test.py::test_request_exec times out under Python 3.9 on macOS 13 (and possibly others?)

This should be fixed by #658 I hope.

Let's rebase this.

Let's rebase this.

Sure. I guess I will rework the test similarly as we did in the sftp case with parametrization once I will touch it.
