Activation keys are not validated.
Description of problem:
Version-Release number of selected component (if applicable):
By following the steps to create a new host group, provide a new
activation key that does not exist.
Steps to Reproduce:
In the step to provide activation keys, we are currently able
to add any value to activation keys. The host group is created without
validating existing activation keys.
A host group is created with non-existing activation keys.
There should be a way to select existing activation keys. The process should
validate the activation key name with existing activation keys.
