ASA prompt checking about netdev

[selfuryon]

@romankuchin Hello! Thank you for your report! I never think about changing prompt with command prompt. I find out that it has several params:

configure mode commands/options:
  cluster-unit     Display the cluster unit name in the session prompt
  context          Display the context in the session prompt (multimode only)
  domain           Display the domain in the session prompt
  hostname         Display the hostname in the session prompt
  management-mode  Display management mode
  priority         Display the priority in the session prompt
  state            Display the traffic passing state in the session prompt

So it can consist more than 3 part with '/' separator. I think that we can omit it all in the _set_base_prompt function except first part (it is usually hostname in the most cases).
I will release new code for ASA in several days after some testing :)

@romankuchin Hello! I changed this code for working with your case. Now it should just work without any workarounds. Can you test it in your environment?

Hello! Reinstalled the module with pip and it works like a charm! No need to keep NetDev sources in the project anymore. Thank you very much!
