Correct RHEL 7 jar names.
Use candlepin-guice in RHEL 7.
Upgrade RESTEasy to what is available in RHEL 7.

Between 2.3.1 and 2.3.7, RESTEasy moved from using Apache's httpclient
to using httpcomponents, so we need to consume that change as well.
Changes in packaging required for RHEL 7.

- RHEL 7 uses 'tomcat' not 'tomcat6'
- RHEL 7 needs asm and cglib explicitly
- Require apache-mime4j equal to 0.6.
  The location of the Message class changed between 0.6 and 0.7 in
  apache-mime4j.  We have to use the 0.6 version or RESTEasy will throw
  ClassNotFoundExceptions.
