Various refactorings

[dgkanatsios]

Minor refactorings on the project.
Details:

1. Removes the sorting for the GameServers in the GameServerBuild controller. The sorting was meant to make for faster deletion, since Initializing and StandingBy servers would be in the first places of the array. However, Initializing could convert to StandingBy which would have changed their ResourceVersion, so there would be conflicts in deleting them. So we decided to remove the sorting and potentially get some CPU cycles back.
2. Simplifies the if checks by combining the non active game servers count into a single variable
3. creates a function for game server deletion, that checks for the resource version before deletion. If the CR has been updated, deletion will return a conflict
4. Updates the addSafeToEvictAnnotation method to add the safe to evict "true" attribute to Initializing GameServer objects
5. removing the sorting revealed another bug where we didn't delete enough game servers when conflicts occurred
6. updating kind version
7. updating controller-runtime to 0.11.1
8. updates the allocate path to make sure that we delete the GameServerDetail when there is an error in Updating the GameServer and setting it to Active
