Feat/delete evaluators or chair

[IanFonzie]

Includes tests? [N]
Updated docs? [N]

Proposed changes:

• Support deleting Evaluators from, or the changing the Evaluation Chair on, an opportunity any time before all individual evaluations have been submitted for all of an opportunity's proposals.
• Add "Evaluation Panel" tab to "edit opportunity" page. This tab supports management of panel until the opportunity has consensus submitted.
• Allow an individual Evaluator so edit a draft evaluation for a proposal, but do not allow them to edit an evaluation after submitting it.
• Allow an Evaluation Chair to edit consensus after it has been submitted, but before the opportunity transitions past the question-evaluation phase.

Additional notes:

• Still some statuses for proposals and opportunities to remove; will address those in the migration for backwards compatibility
