AEP - auto enrollment proxy. Right now we have too many
places to import CA certificates.

1. Local Computer -> Trusted root certificates store
2. Active directory -> domain level group policy
3. publish certs to NTAuthCA store.
4. proxy configuration -> CA certificate to be pasted in base64 format.

We should try to see if we can automate this process.

The ideal fix would be to specify the redhat CA host/port information
and have the AEP configuration UI fetch the entire CA chain and have
it imported in all the necessary places as required.
