This is to make initial installation and testing easier.

Use the --no_hbac_allow option on the command-line to disable this when
doing an install.

To remove it from a running server do: ipa hbac-del allow_all

Resolves #545260

I accidentally pushed the older patch that didn't contain bits for
ipa-replica-install.

This patch adds options --forwarder and --no-forwarders. At least one of
them must be used if you are doing a setup with DNS server. They are
also mutually exclusive. The --forwarder option can be used more than
once to specify more servers. If the installer runs in interactive mode,
it will prompt the user if none of these option was given at the command
line.

This also adds a new option to the template system. If you include
eval(string) in a file that goes through the templater then the
string in the eval will be evaluated by the Python interpreter. This is
used so one can do $UIDSTART+1. If any errors occur during the evaluation
the original string is is returned, eval() and all so it is up to the
developer to make sure the evaluation passes.

The default value for uid and gid is now a random value between
1,000,000 and (2^31 - 1,000,000)

The ipa-replica-install script will setup the DNS if user specifies the
--setup-dns option. It will only add the zone into LDAP if the
cn=dns,$SUFFIX container doesn't exist. For now, however, we do not add
the records.
