[db] Implement new Team and Project entities

[jankeromnes]

How to test

• (I'm not sure how to run the unit test)

• Log in to https://jx-teams-and-projects.staging.gitpod-dev.com/ and check the Console (it should log Teams: [])

• Connect to the DB, manually create a new team, and assign yourself to it:

mysql> insert into d_b_team (id, name, creationDate) values (UUID(), 'YOUR TEAM', '2021-06-03T10:00:00.000Z');

mysql> select * from d_b_team;

mysql> select id, name from d_b_user;

mysql> insert into d_b_team_membership (id, teamId, userId) values (UUID(), 'YOUR-TEAM-ID', 'YOUR-USER-ID');

• Refresh the dashboard -- the console should now log Teams: [{ ... }] (i.e. your team)

Migration seems to work as expected:

(view MySQL tables)

mysql> describe d_b_project;

Now I should probably add a few useful methods to the interfaces and verify they work.

[jankeromnes]

Potential improvements / follow-ups:

• create a new team
• delete a team
• add user to team
• remove user from team

[svenefftinge]

lets add creationTimeas well

[jankeromnes]

Why add a creationTime to a team membership? (Note: There is already the _lastModified field, and I don't expect that we'll modify memberships -- just add or delete.)

[svenefftinge]

I cannot access _lastmodified can I? In the member list I'd like to see joined 2 months ago or so.
