In build_service.rb, let's refactor some param processing code
and comments from the execute() method into a new
filter_label_id_params() method.

While at it let's also add a few comments.

In build_service.rb, let's move most of the force_remove_source_branch
handling code into a new force_remove_source_branch() method.

In issuable_base_service.rb the code processing labels is making
the update() method not as clear as it could be. Let's refactor
this code into a new assign_requested_labels() method.

While at it, lets rename labels_changing? into ids_changing?
as the method is not specific to labels and could be used with
other arrays of ids.

Instead of having to use a local variable in many places in
push_options_handler_service_spec.rb for the same error, let's
refactor this error using a common constant called
'error_mr_required'.
