Contains command classes which may interact with an index / the network.

Unlike its sister module, req_command, this module still uses lazy imports
|
||||
so commands which don't always hit the network (e.g. list w/o --outdated or
|
||||
--uptodate) don't need waste time importing PipSession and friends.
