Add CAPHV to clusterctl as a recognized provider

[belgaied2]

Describe the solution you'd like:
Right now, in order to use CAPHV with clusterctl , the user needs to add a custom configuration under $HOME/.cluster-api/. This can be easily avoid by following the official procedure.

Why do you want this feature:
Adding CAPHV to the clusterctl official provider list will increase visibility of CAPHV.
