Sniffer now requires a HostsSniffer instance as a constructor argument, HostsSniffer has its won Builder helper. Also synchronized accesses to scheduledExecutorService in SnifferTask.
This commit addresses a performance issue in
IndicesClusterStateService#applyDeletedShards. Namely, the current
implementation is O(number of indices * number of shards). This is
because of an outer loop over the indices and an inner loop over the
assigned shards, all to check if a shard is in the outer index. Instead,
we can group the shards by index, and then just do a map lookup for each
index.
Testing this on a single-node with 2500 indices, each with 2 shards,
creating an index before this optimization takes 0.90s and after this
optimization takes 0.19s.

The painless whitelist has a lot of self-checking, in this case, it checks
for missing covariant overrides. It fails on java 9, because LocalDate.getEra()
now returns IsoEra instead of Era: https://bugs.openjdk.java.net/browse/JDK-8072746
To our checker, it thinks we were lazy with whitelisting :)
This means painless works on java 9 again
The database files have been doubled in size compared to the previous files being used.
For this reason the database files are now gzip compressed, which required using
`GZIPInputStream` when loading database files.
You declare them like
```
static {
PARSER.declareInt(optionalConstructorArg(), new ParseField("animal"));
}
```
Other than being optional they follow all of the rules of regular
`constructorArg()`s. Parsing an object with optional constructor args
is going to be slightly less efficient than parsing an object with
all required args if some of the optional args aren't specified because
ConstructingObjectParser isn't able to build the target before the
end of the json object.
This commit fixes a test bug in a global checkpoints integration
test. Namely, if the replica shard is slow to start and is peer
recovered from the primary, it will not have the expected global
checkpoint due to these not being persisted and transferred on recovery.

Due to an error in our current TimeIntervalRounding, two dates can
round to the same key, even when they are 1h apart when using
short interval roundings (e.g. 20m) and a time zone with DST change.
Here is an example for the CET time zone:
On 25 October 2015, 03:00:00 clocks are turned backward 1 hour to
02:00:00 local standard time. The dates
"2015-10-25T02:15:00+02:00" (1445732100000) (before DST end) and
"2015-10-25T02:15:00+01:00" (1445735700000) (after DST end)
are thus 1h apart, but currently they round to the same value
"2015-10-25T02:00:00.000+01:00" (1445734800000).
This violates an important invariant of rounding, namely that the
rounded value must be less or equal to the value that is rounded.
It also leads to wrong histogram bucket counts because documents in
[02:00:00+02:00, 02:20:00+02:00) go to the same bucket as documents
from [02:00:00+01:00, 02:20:00+01:00).
The problem happens because in TimeIntervalRounding#roundKey() we
need to perform the rounding operation in local time, but on
converting back to UTC we don't honor the original values time zone
offset. This fix changes that and adds tests both for DST start and
DST end as well as a test that demonstrates what happens to bucket
sizes when the dst change is not evently divisibly by the interval.
_cat/nodes returns the http address only in 5.x. Would be nice to use as we could drop the jackson dependency, but we care more about being compatible with 2.x.
Not compatible with previous versions as the format of returned http addresses have changed since 2.0.
Also fixed test bug that caused sporadic failures.
