Overhaul of the LDAP module

Closes #738

Major overhaul of the LDAP module to streamline configuration
and error handling. Major new functionality is:

1. Deprecation of old "parameter" var in favor of configure methods
and Inject pattern for all configurable values
2. Automated testing and retry behavior for iffy connections
3. A unit test that utilizes ApacheDS to run an internal test
