Foreman Maintain

Description of problem:

The goal of using "satellite-maintain self-upgrade" is usually for performing a major version upgrade i.e. 6.10 to 6.11 , but when we execute this command on Satellite\Capsule 6.11.1.1 , It tries to enable the maintenance-rpms repo with a wrong version.

Version-Release number of selected component (if applicable):

Satellite\Capsule 6.11.1.1

How reproducible:

100%

Steps to Reproduce:
1. Install the latest most version of Satellite 6.11 and ensure we are on 6.11.1.1-1

2. Run "satellite-maintain self-upgrade"

Actual results:

On RHEL 7:

As we can see, it tries to enable 6.11.2 instead of 6.12 which is not correct.

Expected results:

If the next major version ( 6.12 ) is not available, the command should immediately stop it's execution.

the next major version ( 6.12 ) is available then the command should try to enable the right maintenance repo for 6.12

Additional info:

From a small testing, the main root cause seems to be the way 6.11.1.1 and 6.11.1 is being processed by the .bump method ruby.
