Update Eclipse core prefs
Eclipse Luna overwrites the prefs file, putting all the settings
in alphabetical order and removing comments. This causes the prefs
files to be modified in the git workspace.
Update the file with the version generated by Eclipse to prevent it
from being modified every time.
No settings values are modified by this change.
This also adds another plugin to the lifecycle mapping in the pom.xml which was missed in https://github.com/elastic/elasticsearch/pull/10524.
This enforces that settings are taken into account whichever mean is used to
import the project into Eclipse (manual import, m2e, mvn eclipse:eclipse, ...).
