IMPALA-2563: Support LDAP search bind operations

This patch adds a number of new options for controlling LDAP
by restricting authentication to particular users and/or members of
particular groups:
--ldap_group_filter: comma separated list of authorized groups
--ldap_user_filter: comma separated list of authorized users

There are also options to control how LDAP is searched when applying
these filters:
--ldap_group_dn_pattern
--ldap_group_membership_key
--ldap_group_membership_class

These options were modelled on equivalent options in Hive, see:
https://cwiki.apache.org/confluence/display/Hive/User+and+Group+Filter+Support+with+LDAP+Atn+Provider+in+HiveServer2
https://github.com/apache/hive/tree/master/service/src/java/org/apache/hive/service/auth/ldap

This patch also refactors LDAP related functionality into a utility
class, both to make authentication.cc more manageable and to
facilitate follow up work that will add LDAP authentication options
for the webserver.

Testing:
- Added a FE custom cluster test that sets --ldap_group_filter and
  --ldap_user_filter and verifies expected behavior.
