Network Module: EOS (#16158)
* add new module network * move EOS to NetworkModule * shell.py Python 3.x compatibility * implements the Command class through the connection for eos This implements a new Command class that specifies the cli command and output format. This removes the need to batch commands through the connection * initial add of netcmd module
