How Has This Been Tested?

Throws proper error when wrong tenant name is passed

@karthikk92 can we return the error as in if loop with message

[karthikk92]

nope since if first time adding host entry fails, it will just retry by throwing just error and then finally if not added multiple tries then finally it will throw proper error message when array not added .
