NIFI-950: Perform component validation asynchronously, other
cluster-related performance enhancements
This PR addresses NIFI-950 and a handful of other JIRA's. They were all
done in a single PR because the modifications tend to build upon one another,
and also because this PR really addresses the issue of making nifi clustering
more responsive (in terms of UI) and more stable.

NIFI-950: Make component validation asynchronous
NIFI-950: Still seeing some slow response times when instantiating a large
template in cluster mode so making some minor tweaks based on the results of
CPU profiling
NIFI-5112: Refactored FlowSerializer so that it creates the desired
intermediate data model that can be serialized, separate from serializing. This
allows us to hold the FlowController's Read Lock only while creating the data
model, not while actually serializing the data. Configured Jersey Client in
ThreadPoolRequestReplicator not to look for features using the Service Loader
for every request. Updated Template object to hold a DOM Node that represents
the template contents instead of having to serialize the DTO, then parse the
serialized form as a DOM object each time that it needs to be serialized.
NIFI-5112: Change ThreadPoolRequestReplicator to use OkHttp client instead
of Jersey Client
NIFI-5111: Ensure that if a node is no longer cluster coordinator, that it
clears any stale heartbeats.
NIFI-5110: Notify StandardProcessScheduler when a component is removed so
that it will clean up any resource related to component lifecycle.
