rest: add POST repository/update

Add POST repository/update request to update repository. Repository is
identified by its id, that is provided in the payload.

This can be tested with curl like:
curl -X POST -H "Authorization: $API_KEY"
http://127.0.0.1:8888/repository/update -d '{ "repo_id" : 16, "center" :
3, "name": "newName", "ip":"127.0.0.1" }'
