Fixes two issues:
1. lang-javascript doesn't support `executable` with a `null` `vars`
parameters. The parameter is quite nullable.
2. reindex didn't support script engines who's `unwrap` method wasn't
a noop. This didn't come up for lang-groovy or lang-painless because
both of those `unwrap`s were noops. lang-javascript copys all maps that
it `unwrap`s.
This adds fairly low level unit tests for these fixes but dosen't add
an integration test that makes sure that reindex and lang-javascript
play well together. That'd make backporting this difficult and would
add a fairly significant amount of time to the build for a fairly rare
interaction. Hopefully the unit tests will be enough.
This commit separates the description of the links in the network that are to be disrupted from the failure that is to be applied to the links (disconnect/unresponsive/delay). Previously we had subclasses for the various kind of network disruption schemes combining on one hand failure mode (disconnect/unresponsive/delay) as well as the network links to cut (two partitions / bridge partitioning) into a single class.
Reducing the ping timeouts on a test that does not simulate network failures can cause node disconnects within the test on a slow CI machine.
The test testSearchWithRelocationAndSlowClusterStateProcessing does not expect such disconnects, leading to shard relocation in the test to abort prematurely.
Today in the uncaught exception handler, we attempt to halt the virtual
machine on fatal errors. Yet, halting the virtual machine requires
privileges which might not be granted to the caller when the exception
is thrown for example from a scripting engine. This means that if an
OutOfMemoryError or another fatal error is hit inside a script, the
virtual machine will not exit because the halt call will be denied for
securiry privileges. In this commit, we mark this halt call as trusted
so that the virtual machine can be halted if a fatal error is
encountered in a script.

I also reduced the visibility of a couple classes and renamed/consolidated some
test classes for consistency, eg. removing the `Simple` prefix or using the
`<Type>FieldMapperTests` convention for testing field mappers.
This commit rewords the expect header bug notice to provide the precise
details for the bug arising. In particular, the bug does not impact any
request over 1024 bytes, but instead impacts any request with a body
that is sent in two requests, the first with an Expect: 100-continue
header. The size is irrelevant, and requests with bodies larger than
1024 bytes are okay as long as the Expect: 100-continue header is not
also sent.

Some unused annotation processors caused build-time failures. Instead,
we should just be explicit about which annotation processors we will use
(if any) with additional command-line flags.

Due to a misordering of the HTTP handlers, the Netty 4 HTTP server
mishandles Expect: 100-continue headers from clients. This commit fixes
this issue by ordering the handlers correctly.

testUnknownObjectException used to generate malformed json objects in some cases, due to the existence of arrays as it was not closing the injected object correctly. That is why the test was catching JsonParseException among the exception that are expected to be thrown. That is fixed by tracking where the new object is placed and placing its end object marker to the right level rather than always at the end.
Also introduced a mechanism to explicitly declare objects that won't cause any exception when they get additional objects injected, so that there is no need to override the method anymore as that caused copy pasting of the whole test method. This also makes sure that changes are reflected in tests, as those inner objects are not skipped but we actually check that what is declared is true (no exceptions get thrown when an additional object is added within them.
