Include indirect membership and canonicalize hosts during HBAC rules testing
When users and hosts are included into groups indirectly, make sure that
during HBAC test e fill in all indirect groups properly into an HBAC request.
Also, if hosts provided for test are not specified fully, canonicalize them
using IPA domain.
This makes possible following requests:
ipa hbactest --user foobar --srchost vm-101 --host vm-101 --service sshd
Request to evaluate:
<user <name foobar groups [hbacusers,ipausers]>
service <name sshd groups []>
targethost <name vm-101.ipa.local groups []>
srchost <name vm-101.ipa.local groups []>
