Fixes #881

Changes

• New collection savesearches
  • permissions
  • search query
  • creator
  • label
• SaveSearchHandler
  • Save new search, POST /savesearches
  • Replace saved search with a new one, POST /savesearches/{SearchId}
  • Get all saved searches user has access to, GET /savesearches
  • Get specific search by Id, GET /savesearches/{SearchId}
  • Delete a specific search, DELETE /savesearches/{SearchId}
  • Permission functions, /savesearches/{SearchId}/permissions

Examples Request

POST /savesearches

{
    "label" : "Example Search",
    "search": {
        "return_type" : "sessions"
    }
}

A replace would look identical except the request url would be POST /savesearch/{SaerchId}

The replace method can directly take the response body of GET /savesearches/{SearchId}
