Thread safety, misc fixes, and refactoring (#51)

Browse source 
* Changing incorrect license in some source files.

* Changing CreateService to mimic CreateJob by setting the batch size to the instance count.

* Changing Getcerts to GetCerts to match the style of the rest of the codebase.

* Overhauled error handling. Backoff now recognizes temporary errors and continues to retry if it finds one.

* Changed thrift function call wrapper to be more explicitly named and to perform more safety checks.

* Moved Jitter function from realis to retry.

* API code is now more uniform and follows a certain template.

* Lock added whenever a thrift call is made or when a modification is done to the connection. Note that calling ReestablishConn externally may result in some race conditions. We will move to make this function private in the near future.

* Added test for Realis session thread safety. Tested ScheduleStatus monitor. Tested monitor timing out.

* Returning nil whenever there is an error return so that there are no ambiguities.

* Using defer with unlock so that the lock is still released if a panic is invoked.
