Adds support for indexing into lists and arrays with negative
indexes meaning "counting from the back". So for if
`x = ["cat", "dog", "chicken"]` then `x[-1] == "chicken"`.
This adds an extra branch to every array and list access but
some performance testing makes it look like the branch predictor
successfully predicts the branch every time so there isn't a
in execution time for this feature when the index is positive.
When the index is negative performance testing showed the runtime
is the same as writing `x[x.length - 1]`, again, presumably thanks
to the branch predictor.
Those performance metrics were calculated for lists and arrays but
`def`s get roughly the same treatment though instead of inlining
the test they need to make a invoke dynamic so we don't screw up
maps.

Lucene 6.3 is expected to be released in the next weeks so it'd be good to give
it some integration testing. I had to upgrade randomized-testing too so that
both Lucene and Elasticsearch are on the same version.
Converts docs for `_cat/segments`, `_cat/plugins` and `_cat/repositories`
from `curl` to `// CONSOLE` so they are tested as part of the build and
are cleaner to use in Console. They should work fine with `curl` with
the `COPY AS CURL` link.
Also swaps the `source` type of the response from `js` to `txt` because
that is more correct. The syntax highlighter doesn't care. It looks at
the text to figure out the language. So it looks a little funny for `_cat`
responses regardless.

On some systems, cgroups will be available but not configured. And in
some cases, cgroups will be configured, but not for the subsystems that
we are expecting (e.g., cpu and cpuacct). This commit strengthens the
handling of cgroup stats on such systems.

This change adds a TypesQuery that checks if the disjunction of types should be rewritten to a MatchAllDocs query. The check is done only if the number of terms is below a threshold (16 by default and configurable via max_boolean_clause).
This allows you to whitelist `localhost:*` or `127.0.10.*:9200`.
It explicitly checks for patterns like `*` in the whitelist and
refuses to start if the whitelist would match everything. Beyond
that the user is on their own designing a secure whitelist.
This commit fixes two issues with the slow log docs:
- clarifies that these settings are per index
- updates index slow log configuration for Log4j 2

It is important that folks understand that snapshot/restore isn't
for archiving. It is appropriate for backup and disaster recovery
but not for archival over long periods of time because of version
incompatibility.

Uses the new sorting (#20658) in the `_cat` API to support all use
cases natively. We can still resort to piping things through `sort`
if we need to, but we don't have to for basic stuff like sorting!
* Adding built-in sorting capability to _cat apis.
Closes#16975
* addressing pr comments
* changing value types back to original implementation and fixing cosmetic issues
* Changing compareTo, hashCode of value types to a better implementation
* Changed value compareTos to use Double.compare instead of if statements + fixed some failed unit tests
Removes a non-existant file from the non-`// CONSOLE` list. If you
remove all the non-`// CONSOLE` snippets from a file it must be
removed from the whitelist for the build to pass. Removing the file
entirely counts as removing the snippets.
