Today, when loading plugins from the classpath we take the enumeration
given to us by the classloader and attempt to load every URL. This can
cause issues as certain classloaders, such as groovy's, will return the same
URL multiple times in the enumeration. When this happens, startup can fail
with guice errors as bindings have already been registered.
To workaround this, we create a set from the URLs returned by the classloader
to provide uniqueness.
We had some code that created a TermQuery instead of a TermsQuery when there
was a single term, which is not useful anymore now that TermsQuery rewrites to
a disjunction when there are few terms:

Simplification of MultiValueMode by removing the apply and reduce
methods for each mode. This creates a more consistent environment for
sorting methods since all sorting must now go through select methods.
This allows for better error handling and better encapsulation for
sorting fields with multiple values.
Note that apply and reduce had inconsistencies in the code base
prior to this change since different calls were assuming that the
accumulator for apply was the first input versus the second input.
Also added is an UnsortedNumericDoubleValues interface to allow
customized values to be input into the different sort modes. This
prevents the need for apply/reduce outside of MultiValueMode.

In order to get some information if the TTL purger thread could
successfully delete all documents per bulk exection, this commit
adds some logging. TRACE level logging will potentially contain
a lot of information about all the bulk failures.
Closes#11019
The Sampler agg was not capable of collecting samples for more than one parent bucket.
Added a Junit test case and changed BestDocsDeferringCollector to internally maintain collections per parent bucket.
Closes#10719
This option is broken currently since it potentially interprets an incoming
binary value as compressed while it just happens that the first bytes are the
same as the LZF header.
Sigar can only be disabled by removing the binaries. This is tricky for our
tests and might cause a lot of trouble if a user wants or needs to do it.
This commit allows to disable sigar with a simple boolean flag in the settings.
Closes#9582
