Remove the key_filename parameter from the call to Paramiko's
connect(). It's user-dependent, and the current DevOps implementation
relies on having a SSH_AUTH_SOCK in the environment, anyway.

Add a wrapper around urlparse() and Paramiko's connect() function, in
order to log some more info in case an exception is thrown.

Take a positional uri argument to the constructor of ExecContext,
forcing SSHClient to follow suit. The latter was instantiated with a
hostname as only argument up to now, which still works as a special
case of an uri.

Code beautification chore: Move the public methods of SSHClients to
the bottom of the class to be consistent with other classes.

Align the prototype of SSHClient.run_cmd() to ExecContext.run(). This
is a push towards making the SSHClient code an ExceContext, too. Some
arguments still log a warning or outright raise NotImplementedError.

Make SSHClient accept a list of strings for the cmd argument to align
with the other run_cmd() functions in jw-pkg.

Most run_xxx() return stdout and stderr. There's no way, really, for
the caller to get hold of the exit code of the spawned executable. It
can pass throw=true, catch, and assume a non-zero exit status. But
that's not semantically clean, since the spawned function can well be
a test function which is expected to return a non-zero status code,
and the caller might be interested in what code that was, exactly.
The clearest way to solve this is to return the exit code as well.
This commit does that.

This is a code maintenance commit: some run_xxx() helper functions
take a string, some a list, and some just digest all arguments and
pass them on as a list to exec() to be executed. That's highly
inconsistent. This commit changes that to list-only.
Except for the run_cmd() method of SSHClient, which is still run as a
shell method, because, erm, it's a shell. Might be changed in the
future for consistency reasons.

run_cmd() is synchronous. Now that all commands are asynchronous, we
can await it, so rewrite it to be asynchronous, too.
Other changes:
- Make it return stderr as well in case its needed
- Drop into a pseuto-tty if
- cmd_input == "mode:interactive" or
- cmd_input == "mode:auto" and stdin is a TTY
- Add argument env, defaulting to None. If it's a dict, it will be
the environment the command is run in
This entails making all functions using run_cmd() async, too,
including run_curl(), get_username() and get_password().
