Refactor(anta.tests): Augment VerifySSHStatus inputs to support a different VRF and an expected state

[gmuloc]

          VerifySSHStatus test should be augmented to support a different VRF and an expected state in the future (with defaults being disabled / default to be backward compatib;e)

Discussed with @vitthalmagadum and @geetanjalimanegslab on a call:

The command fails with VRF default today

net-cloud(config-mgmt-ssh-vrf-BLAH)#show active
management ssh
   vrf BLAH
      no shutdown
      !
      tunnel BLAH
inet-cloud(config)#show management ssh vrf BLAH
User certificate authentication method: none (trusted CA not configured)
SSHD status for VRF BLAH is disabled
SSH connection limit is 50
SSH per host connection limit is 20
FIPS status: disabled

inet-cloud(config)#show management ssh
User certificate authentication method: none (trusted CA not configured)
SSHD status for Default VRF is enabled
SSH connection limit is 50
SSH per host connection limit is 20
FIPS status: disabled

inet-cloud(config)#show management ssh vrf default
% VRF default not found under SSH management  <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

When vrf default is configured, the command is valid but the output seems wrong (as different than entering the command without VRF)

inet-cloud(config-mgmt-ssh)#show active
management ssh
   vrf BLAH
      no shutdown
      !
      tunnel BLAH
   !
   vrf default
