Do not allow combination of --context with (project, app and component) flags

[kadel]

based on: #2387 (comment)_

It can be confusing when --context flag is used together with one or more --project --app --component flags.

We should add a check that doesn't allow the use of --context with --app or --project or --component.

this will break alot of our tests, as currently we are using --context with --project and --app for odo create. and maybe it makes sense to have this possible for odo create because a user might want to use a specific app and a project while creating the config.yaml in the --context directory? @kadel

yes, we have to fix those tests!

That is a good point. For odo component create it makes sense to combine --context and with --project and/or --app. But not for anything else.
