error out of upgrade as soon as a bad gear configuration is detected
Check for cartridge IDENT before starting gear upgrade process

https://bugzilla.redhat.com/show_bug.cgi?id=1077378
Gear upgrade should not fail when OPENSHIFT_*_IDENT env variable not present.
Multiple fixes
 - Checking the provides list for cartridge matches for Configure-Order
 - Skipping rollback for configure and similar operations in case of a new gear creation. Instead, we will just delete the gear
 - Fixing exception raising logic on rollback success/failure
move some node requires to diy cartridge dependencies

fix typo
fix bz1076722 - routes.json may have frontend extensions to fqdn
