This has been a basically dead code path since removal of non-remote
channels:

Either a user chooses to not move files (overriding move_files to False)
and the push_file was not used.

Or the default push_file was used, but:
* this is always LocalChannel now (PR #3677)
* the script directory is always the local script directory (PR #3688)
and so the local channel code always skips making a copy

This commit simplies all of that away into using the script path directly
with putting it through the above complicated no-op.

This removes push/pull support from channels.

All the HPC providers used channel.push_file to push their batch scripts
to the (no-longer) remote system. This has been a basically dead code
path since removal of non-remote channels:

The channel is always a LocalChannel now (PR #3677)
The "remote" script directory is always the local script directory (PR
#3688) and so `LocalChannel.push_file` always skips making a copy and
returns the path it was given without further action.

So all the removed code is a no-op, and this PR simplifies that into
nothing.

# Changed Behaviour

Some providers had an option to let users decide if scripts (and other
files) would be pushed/pulled to the remote system. Those options are
removed by this PR.
