Refactor Task: Remove functions for all collection url attributes

[lifeBCE]

There is currently a combination of url attribute assignments, within all collections, using a simple concatenated string and others using a function to return a simple concatenated string. We should change all those that use a function to not use a function.

Example:

url: function(options){return Common.apiUrl + '/api/v1/continuous_integration_servers/org/' + sessionStorage.org_id;}
