remote-user: Fix .conf migration in %post

If the remote-user auth plug-in is installed but is not enabled at the
time of an upgrade, its httpd configuration file may not be present.  In
order to avoid causing an error during a package upgrade, only modify
the file if it is present.
Bug 971586

Set up cron's PATH to use primary cartridge's *_PATH_ELEMENT so that
cron can use the cartridge's executables.
Mimic rhcsh logic more closely

Ensure the primary cartridge's *_PATH_ELEMENT wins
haproxy_ctld_daemon.rb: Fix backtrace option

The haproxy_ctld_daemon.rb script in the haproxy cartridge had a typo:
':backgrace' instead of ':backtrace'.

This typo appears to have been present since haproxy_ctld_daemon.rb was
introduced in commit ee8cebbe1adb351a3b80ca3fda4f047aee8fac1b.
openshift_facts.rb: sort cart_list

In the JBoss cartridges' standalone.conf file, use OPENSHIFT_JBOSSAS_DIR
or OPENSHIFT_JBOSSEAP_DIR as appropriate to set the value of CART_DIR.

move_gear: drop outdated rollback code

Don't call the remove-httpd-proxy hook when rolling back a failed
move_gear operation in MCollectiveApplicationContainerProxy.

The remove-httpd-proxy hook was removed from the v2 cartridge model, so
calling the hook results in calling an undefined method in the cartridge
model when v2 cartridges are used.  Furthermore, the platform now takes
care of configuring the port proxy, so it is no longer necessary for
move_gear to invoke remove-httpd-proxy.  Commit
7d458f76116a0b72b651155d1178ad3d70398104 already dropped the call in
move_gear to the "move" hook, which invoked the deploy-httpd-proxy hook,
which is also handled by the platform now.

This commit fixes Bug 987218.
