* As part of the ElasticSearch v6 upgrade:
** uploaded ElasticSearch 6.5.4 packages to reprepro [0]
** Adapted the ElasticSearch puppet module [1]
** Tested that we can run multiple ElasticSearch clusters on same hardware [2]
* We discovered that the Maven Wrapper does not support
XDG_CACHE_HOME, so we updated java8: to actually use the new image;
fixing the mvn wrapper cache issue [3]
* Upon unpacking the Greek analysis chain, we found that the filter
isn't properly handling language-specific lowercasing in language
analyzers; fixed it by adding Greek empty-token filter and keep
lang-specific lowercasing [4]
* As part of the lang-specific lowercasing, we also upgraded the ICU
normalization [5] [6]
* We decided we should use a better/cleaner approach for icinga
elasticsearch check and merged http and https elasticsearch icinga
checks into one [7]
* We also updated the alerts for mjolnir daemons, so we can tell when
it starts misbehaving [8]
