Rollup was using a historical `rollup` doc type, when we should be using
`_doc` so that it is forward-compatible with the removal in 8.0

This is required so the Logstash Centralized Configuration Management UI in Kibana may make the GET / request to Elasticsearch and retrieve the cluster UUID. It then uses this cluster UUID to make a call to a Kibana Monitoring API to retrieve a list of pipelines from Monitoring. In order for the Kibana Monitoring API request to succeed, the logged-in user needs to have the built-in monitoring_user role anyway, so we give this role the cluster:monitor/main privilege.

Currently there is a hardcoded check against 10000, which
is the default value of the max_result_window setting. This
is a relic of the past. Removing this hardcoded validation
means we respect the setting so that a user may alter it
when appropriate.

Currently numDocs() is computed lazily, but this doesn't help since
BaseCompositeReader calls numDocs() on its sub readers eagerly. This may cause
performance issues since every time we wrap a reader with DocumentSubSetReader
(which means for every query when DLS is enabled) we need to recompute the
number of live documents, which runs in linear time with the number of matches
of the role query.
Not computing numDocs() eagerly in DocumentSubSetReader might help, but it
would also be fragile since callers of this method still usually assume that
it runs in constant time. So I am proposing that we add a cache of the number
of live docs in order to decrease the performance hit of document-level
security. I would expect this cache to be efficient as it will not only reuse
entries in-between refreshes, but also across refreshes for segments that
haven't received any new updates.

Renaming should hopefully make it more clear that this is the size
of pages to process during rolling up, nothing to do with the size
of the various groups, metrics, etc.

This constructor was actually never used, other than in tests, and even then,
there is no need for a custom period type as the human-readable toString value
will suffice.

Adds `value_count` as one of the accepted metrics. The caveat is that
it only accepts numeric values for two reasons:
- Job validation at creation makes sure all metrics are numeric fields.
Changing this would require new syntax (or disallowing anything but
value_count on mixed fields)
- when `toBuilders()` is called, we have to supply a ValueSource to
the ValueCountBuilder, and we don't know what the field type is at that
time.
These are both fixable, but relatively more involved. I think numeric-only
is a reasonable limitation to start with

We specify an alias for signing key, but when we just have
a single key in key store this is an additional setting which
is annoying. This PR addresses this issue by making it optional.
- Changes in SamlRealmSettings to make signing/encryption
key alias optional
- Checks if none of the keys are useful for given operation
signing or encryption throws an error.
- Checks for no of aliases in key-store, if more than one and alias
is not specified throws error.
- If an alias is not specified and there is just one alias in
keystore then use it as the credential.
- Unit Tests
Note: A side effect of this change the above-mentioned behavior is
it's also applicable for encryption keys currently, but it is going
to change when fixing elastic/x-pack-elasticsearch#3980 for supporting multiple encryption keys.

This commit changes the combination of multiple automatons representing
a pattern so that the result of each step is minimal. Previously, the
code unioned the automata and performed the minimization operation
after all of the automata had been combined. This resulted in patterns
with lots of overlap causing a TooComplexToDeterminizeException even
though the end result could be a automaton that is total. Minimizing
the automata as we go, allows us to build an automata that could not
previously be built at the cost of additional operations. Automata are
typically cached in the security code, so the net performance impact
should be minimal.

This PR adds logic to ensure that the fields (and field types) configured
in the Rollup Job are present in the index/indices specified by the job's
index pattern. If a field is missing, or is not aggregatable, it
will throw an exception before the job is created.
This is important for user-friendliness, because otherwise the user
only discovers an issue with mapping when the job is started and
fails to rollup correctly (and only really noticeable by looking at logs,
since it's a runtime failure).

All ML objects stored in internal indices are currently parsed
strictly. This means unknown fields lead to parsing failures.
In turn, this means we cannot add new fields in any of those
objects (e.g. bucket, record, calendar, etc.) as it is not
backwards compatible.
This commit changes this by introducing lenient parsing when
it comes to reading those objects from the internal indices.
Note we still use strict parsing for the objects we read from
the c++ process, which is nice as it guarantees we would detect
if any of the fields were renamed on one side but not the other.
Also note that even though this is going in from 6.3, we cannot
introduce new fields until 7.0.

If a user has roles that grant access to a large number of disparate
index patterns, then the resulting Automaton can become large and
too costly to determinise. This happens rarely, and is usually a sign
of a poorly implemented security model, so we have no immediate plans
to change the implementation. However the resulting error message is
not clear and does not provide sufficient information for users to
resolve the underlying problem.
This commit catches the underlying exception and provides a more
specific error message, with DEBUG logging of the offending index
patterns.

If there are multiple jobs that are all the "best" (e.g. share the
best interval) we have no way of knowing which is actually the best.
Unfortunately, we cannot just filter for all the jobs in a single
search because their doc_counts can potentially overlap.
To solve this, we execute an msearch-per-job so that the results
stay isolated. When rewriting the response, we iteratively
unroll and reduce the independent msearch responses into a single
"working tree". This allows us to intervene if there are
overlapping buckets and manually choose a doc_count.
Job selection is found by recursively descending through the aggregation
tree and independently pruning the list of valid job caps in each branch.
When a leaf node is reached in the branch, the remaining jobs are
sorted by "best'ness" (see comparator in RollupJobIdentifierUtils for the
implementation) and added to a global set of "best jobs". Once
all branches have been evaluated, the final set is returned to the
calling code.
Job "best'ness" is, briefly, the job(s) that have
- The largest compatible date interval
- Fewer and larger interval histograms
- Fewer terms groups
Note: the final set of "best" jobs is not guaranteed to be minimal,
there may be redundant effort due to independent branches choosing
jobs that are subsets of other branches.
Related changes:
- We have to include the job's ID in the rollup doc's
hash, so that different jobs don't overwrite the same summary
document.
- Now that we iteratively reduce the agg tree, the agg framework
injects empty buckets while we're working. In most cases this
is harmless, but for `avg` aggs the empty bucket is a SumAgg while
any unrolled versions are converted into AvgAggs... causing a cast
exception. To get around this, avg's are renamed to
`{source_name}.value` to prevent a conflict
- The job filtering has been pushed up into a query filter, since it
applies to the entire msearch rather than just individual agg components
- We no longer add a filter agg clause about the date_histo's interval, because
that is handled by the job validation and pruning.

This changes `_xpack/monitoring/_bulk` to fundamentally behave in the same
way as `_bulk` and never return 202 when data is ignored (something
`_bulk` cannot do). Instead, anyone interested will have to inspect the
returned response for the ignored flag.

This change disables security for trial licenses unless security is
explicitly enabled in the settings. This is done to facilitate users
getting started and not having to deal with some of the complexities
involved in getting security configured. In order to do this and avoid
disabling security for existing users that have gold or platinum
licenses, we have to disable security after cluster formation so that
the license can be retrieved.
