CORE-20763 - Eliminate support of DurableStream

[filipesoliveira]

DurableStream functionality is redundant in REST API and is never used in production to deliver any sort of feed. Therefore any references to net.corda.rest.durablestream have been removed from the codebase.

The following tests must be green before merging the PR:
