[RHEL/6] Add initial USGCB kickstart for Red Hat Enteprise Linux 6 Server variant
[RHEL/6/kickstart] Rename usgcb-server-ks.cfg to usgcb-server-with-gui-ks.cfg to detail
                   it will create Red Hat Enterprise Linux 6 Server with GUI instances as
                   a result. Also add a note explaining why use of latest Git repository
                   content should be preferred for now rather than use of RHEL-6 benchmark
                   from native RHEL-6 scap-security-guide RPM package.
[RHEL/6/kickstart] Update NOTE wrt to cloning upstream repository content based
                   on Shawn's proposal. Thanks.

[RHEL/6] Modify RHEL-6 remediation fixes for service enabled / disabled
         rules to use full path when referring to 'chkconfig' &
         'service' commands instead of just basenames to prevent remediation
         script errors. Fixes issue #313.

[RHEL/6] Use full path for 'chkconfig' & 'service' commands in RHEL-6 service related remediation scripts
[shared, RHEL/6, RHEL/7] Fix 'Uninstall net-snmp Package' rule & add a (shared version) of remediation for it.

Bugfixes - There are multiple issues with the current form of 'Unistall net-snmp Package' rule:
* rule ID "uninstall_net-snmp" doesn't follow the "package_net-snmp_removed" template (fixed in XCCDF
  and also in all profiles that were referencing that rule)
* the package check macro speaks about "net-snmpd" instead of 'net-snmp' (fixed)
* RHEL/7 & Fedora packages_removed.csv templates doesn't speak about already present net-snmp
  OVAL check (fixed)

Enhancements:
* modify Fedora XCCDF to start using the (already present) OVAL
* add shared/ version of the remediation & link / start using it from RHEL/{6,7} & Fedora directories
