* api: Add an endpoint to list a particular member of team.
* models: Rename `GetUserTeams()` to `GetUserOrgTeams()` in `org_team` model.
`GetUserTeams()` sounds a bit misnomer since it actually returns
the teams that user belongs to in a given organization rather than
all the teams across all the organization that the user has joined.
* models: Add `GetUserTeams()`.
Returns all the teams that a user belongs to.
* api: Add an endpoint for GET '/user/teams'.
A GET request to this endpoint lists all the teams that a user
belongs to.
