The org.codelibs.elasticsearch.module.lang-painless does not work any
more with ES 7.12.x.

Only this package actually made the Painless plugin available as Maven
dependency. elasticsearch-scripting-painless-spi only makes the SPI
available without packaging the actual plugin.

So, right now we have no dependency to get Painless for unit tests.

In "normal" ES setups, Painless within Signals should continue to work.

This should make this test a bit more resilient against race conditions

Introduces a new REST API which allows users to create auth tokens. These tokens can be used for authenticating the user at Search Guard without having to use the normal user credentials. This is typically used by external tools which authenticate ob behalf of the user.

Auth tokens can have restricted permissions and a restricted lifetime.

This is necessary to support aggregations sorted by key.

NOTE: This does now need reflection. As this is not very clean and can easily break, this should be considered only as temporary fix.

Exclude junit5 from testscope as we are using Junit 4 and this makes ugly problems in eclipse
