adds two new plugins that use ansible-connection for persistence (#18572)
* adds new connection plugin `network_cli` which builds on paramiko * adds new plugin `terminal` used for manipulating network_cli terminals * adds new field to play_context `network_os` settable as ansible_network_os This commit adds the plugins necesary to establish a persistent cli connection to network devices of ssh. It builds on the paramiko connection plugin to create a shell environment that will persistent through ansible-connection. The `newtork_cli` plugin then uses the network_os in the instance of PlayContext to load the appropriate network OS environment plugin for handling opening and closing of shells as well as privilege escalation.
