Ganesh Nalawade 8472a53bea Add prompt check in action plugin for network platform (#32787)
* Add prompt check in action plugin for network platform

In case of ignore_errors for a wrong configuration
the prompt is left in configuration mode and moved to
next task, if the next taks requires prompt to be
in operational state it results in failure.
Hence add a check to ensure right prompt at start of
each task run.
