a couple of robustness enhancements to the apache plugin:
BZ 656449 - use the matching algorithm between SNMP values and augeas nodes also
when matching the vhost node by resource key, because resource key
in RHQ 3 is based on the SNMP value.
BZ 652247 - Log the SNMP errors only on DEBUG level during discovery because SNMP isn't
required for it to work.
BZ 656476 - Do not fail the discovery if a non-existent directory is used in an Include directive
BZ 652247, BZ 656491 - Do not choke on invalid/unresolvable hostnames in VirtualHost or ServerName directives
Verified on JON 2.4.1 build #28 (Revision: 10957) Configured httpd.conf with invalid hostname for ServerName in the main server configuration. Observation: All the vhosts and the Main server and discovered Bookkeeping - closing bug - fixed in recent release. Bookkeeping - closing bug - fixed in recent release.
