Feature: Hide Configure if GITLAB_MONITOR_CONFIG present

[martincollado]

When you deploy a container pre configured with custom configuration attached via GITLAB_MONITOR_CONFIG, would be interesting to provide a mechanism to not allow the config modification.

I can think of two possible options:

• If GITLAB_MONITOR_CONFIG is present
• Providing the option on the config settings inside the GITLAB_MONITOR_CONFIG, similar to configurationDiabled: true/false

I'm not an Vue expert developer, but I could try to submit a PR to it.

That would be a nice addition and I'd be happy to review a PR from you :)
