* 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.
* comments: Fix an incorrent DOM element selection.
This commit fixes a bug that was causing text from previously edited
comment to get saved when two comments were edited one after other.
Text area with id of `#content` isn't unique on the page but it was
being treated as unique by the event handling code.
Fixes: #5581.
* templates: Remove `id` from textarea in commit edit form.
An element is assigned an `id` only if it is unique for the whole page
but in this case there can be multiple textarea so it should have one.
