[DEV] Milestone Management

[elkhawajah]

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)
• Updated deleting product phase to sync it in ES

DB Script to execute :
migrations/20210718_project_phase_member_table.sql
migrations/20210802_project_phase_approval_table.sql

@elkhawajah before merging we have to get this updated as per the review from @maxceem

it looks like this new code would return phase members together with PII information like first name, last name and email to any user
while previously we restricted such info only to admins
there is already a reusable method util.getObjectsWithMemberDetails which can populate member details based on who made the req here are the examples:
