It is rarely used and was not consistently handled by different distributions anyway.
This commit also adds a test for specifying CONF_DIR when installing plugins and
starting elasticsearch.

Mappings and many modules are not needed here compared to AbstractQueryTestCase, as we will never call toQuery in this other test. Parsing is independent from indices and types as well.
package installation creates the plugin directory already so when a plugin
is installed it prints the additional line
Plugins directory [/tmp/elasticsearch/plugins] does not exist. Creating...
For minScore and terminateAfter we can just rely on defaults set to SearchSourceBuilder. Also simplified toString representation of CountRequestBuilder
Plugin cli tools configures logging with whatever is in the logging.yml.
If a file appender is configured for any of the logs this will cause creation
of an empty log file. If a plugin was for example installed as root it will
create empty logs at es.home/logs.
This is problematic when for example plugins are installed as root and es is run
as service. Logs will then be created in /usr/share/elasticsearch/logs
and can later not be removed by for example dpkg -r or -purge.
To avoid this, configure the logger to use an appender that writes to the same
output that plugin cli tool does. This allows other components that are called
from Plugin cli tool to write to the same terminal that plugin cli tool writes to
by using the logging mechanism already in place.
The logging conf is not read at all pb plugin cli tool.
As a side effect, the loging level for components that are called
from the plugin command such as the jar hell check can now be configured
with -Des.logger.level which makes it easier to debug the jar hell check.
The field is optional everywhere else but in the serialization methods, which causes problems. Also expanded tests so that they can catch this type of problem.
Closes#13963
With 2.0, we now bind to `localhost` by default instead of binding to the network card and use its IP address.
When the discovery plugin gets from AWS API the list of nodes that should form the cluster, this list is pinged then. But as each node is bound to `localhost`, ping does not get an answer and the node elects itself as the master node.
`network.host` must be set.
Closes#13589.
