This is part of Milestone management project/sprint for Topcoder conenct, an initiative to improve the UX in TC Connect for project progress/plan communication with the customers.

This push contains :

• Add new cross ref table between Topcoder Users and TC Connect Project Phase.
• Updated Phases api endpionts to include members field which represents the copilot user ids, so when pulling a phase or project phases we get members array
• Added new endpoint to update Phase copilots by passing userIds field to store the association
• Updated Get Phases endpiont to have memberOnly param to get only phases the authorized member is part of
• Updated maxPhaseProductCount to 100, so we allow creating multiple products (challenges) per product (Milestone)
• Storing challenge id in the Phase.Product.Details json array (the string used in details is configured in tc connect and work manager app)
• Customer approval with In Review/Reviewed status (don't allow approval if phase is not In Review)
