Adding autopause APIs to future (#110)

Browse source 
* Updating thrift definitions to add autopause for batch based update strategies.

* Adding batch calculator utility and test cases for it.

* Adding PauseUpdateMonitor which allows users to poll Aurora for information on an active Update being carried out until it enters the ROLL_FORWARD_PAUSED state.

* Tests for PauseUpdateMonitor and VariableBatchStep added to the end to end tests.

* Adding TerminalUpdateStates function which returns a slice containing all terminal states for an update. Changed signature of JobUpdateStatus from using a map for desired states to a slice. A map is no longer necessary with the new version of thrift and only adds complexity.
