* Add connection=netconf in individual roles for modules that run using netconf connection
plugin
* Add connection=network_cli for junos_netconf and junos_command
at applicable places
junos integration test fails intermittently after task enables netconf
on the remote host and the second task tries to create a persistent
connection. Add a delay after the first task to ensure netconf is up
running on remote host.
