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.

* CreateService and StartJobUpdate do not continue retrying if a timeout has been encountered
by the HTTP client. Instead they now return an error that conforms to the Timedout interface.
Users can check for a Timedout error by using `realis.IsTimeout(err)`.
* New API function VariableBatchStep has been added which returns the current batch at which
a Variable Batch Update configured Update is currently in.
* Added new PauseUpdateMonitor which monitors an update until it is an `ROLL_FORWARD_PAUSED` state.
* Added variableBatchStep command to sample client to be used for testing new VariableBatchStep api.
* JobUpdateStatus has changed function signature from:
`JobUpdateStatus(updateKey aurora.JobUpdateKey, desiredStatuses map[aurora.JobUpdateStatus]bool, interval, timeout time.Duration) (aurora.JobUpdateStatus, error)`
to
`JobUpdateStatus(updateKey aurora.JobUpdateKey, desiredStatuses []aurora.JobUpdateStatus, interval, timeout time.Duration) (aurora.JobUpdateStatus, error)`
* Added TerminalUpdateStates function which returns an slice containing all UpdateStates which are considered terminal states.
