ab4e910c52 Use separate variable for client fetch in kdcpolicy

c5f32165d6 Add Authentication Indicator Kerberos ticket policy options
For the authentication indicators 'otp', 'radius', 'pkinit', and
'hardened', allow specifying maximum ticket life and maximum renewable
age in Kerberos ticket policy.

The policy extensions are now loaded when a Kerberos principal data is
requested by the KDC and evaluated in AS_REQ KDC policy check. If one of
the authentication indicators mentioned above is present in the AS_REQ,
corresponding policy is applied to the ticket.

15ff9c8fec Implement user pre-authentication control with kdcpolicy plugin
We created a Kerberos kdcpolicy plugin to enforce user
pre-authentication policy for newly added pkinit and hardened policy.

In the past version of freeIPA, password enforcement exists but was done
by removing key data for a principal while parsing LDAP entry for it.
This hack is also removed and is now also enforced by kdcpolicy plugin
instead.
