[andrewwdye]

TL;DR

Populate driver and executor tolerations from optional pod templates. This is an initial step narrowly focused on pod tolerations, to be followed by a more generic solution that handles all pod template functionality.

Complete description

This change builds on optional Spark pod template changes added in flyteorg/flyteidl#450. For now appends tolerations from the driver and executor pod templates, if any, to the defaults used to build the SparkApplicationSpec. A follow up PR will refactor the Spark plugin and pod_helper.go to reuse ToK8sPodSpec in order to consume other aspect of pod templates, as is done for other plugins.
