Netty: Support to bind on multiple host/port pairs

This patch allows to create several netty bootstrap, each of which
listening on different ports. This will potentially allow for features
to listen to different network interfaces for node-to-node or node-to-client
communication and is also the base to listen to several interfaces, so that those
can be used to speed up cluster communication in the future.

Closes #8098
Test: Fix netty multiport tests

Ensuring, that even in local mode, netty is started appropriately.
Core: fix index throttling to notice a change to max_merge_count on the next merge start/finish

Allow setting individual breakers to "noop" breakers

This adds a NoopCircuitBreaker, and then adds the settings
`indices.breaker.fielddata.type` and `indices.breaker.request.type`,
which can be set to "noop" in order to use a breaker that will never
break, and incurs no overhead during computation.

This also refactors the tests for the CircuitBreakerService to use
@Before and @After functions as well as adding settings in
ElasticsearchIntegrationTest to occasionally use NOOP breakers for all
tests.
Update plugins.asciidoc

Added Vietnamese Analyser to plugins page

Closes #6647
