DevServer: Add a new devserver call to list all control files' content. Now when a suite job is created, it calls devserver to list all control files' path, and then call devserver X times to get the content of each control file, where X equals to the length of the control file list. Since a suite job may fetch more than 1000+ control files, and all the thouands of calls are made over ssh. It's significantly slower than previous directly calling devserver by http. The new call 'list_suite_controls' goes through the lists of all control files for a suite and a build, and return the contents of these control files.
