Executor abstraction (#384)

This change adds a layer of abstraction over poolmgr. Poolmgr is now just one of the ways to turn a function into a service; other implementations will be added. The executor abstraction is a uniform API over all these implementations. * Executor layer added on top of pool manager * Removed the external server for executor * Minor changes to keep existing semantics as much possible * Separating the executor vs. poolmgr backend functionality and associated data members * Executor logic separated from Poolmgr backend completely, placeholder for new backend * Changed references to poolmgr in tests * Moved poolmgr to it's package, as a side effect moved Cache to its's package (was causing cyclical dependency) and had to make some data structures exposed outside package * Rebased from master and changed references to tpr -> crd * Executor layer added on top of pool manager * Executor logic separated from Poolmgr backend completely, placeholder for new backend * Changed podName to a generic objectReference in fscache (#391) Changed podName to a generic objectReference in function service cache implementation. * Moved poolmgr to it's package, as a side effect moved Cache to its's package (was causing cyclical dependency) and had to make some data structures exposed outside package * Rebased from master and changed references to tpr -> crd * Merged from master with latest changes * Removed stale executor service & deployment from previous merge * Addressed review comments, still testing some areas
