As the title says, a way to exclude default plugins. People may not want or need all of the plugins that are included by default in Open MCT.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Could be another plugin? Possibly one that you can pass in default plugin names to exclude from the create menu. Or, possibly an option to pass plugin names to openmct.start() that would not install the plugins at all if they're included, this would be a more thorough method than the first.

Describe alternatives you've considered
