Fix m2e Eclipse Integration

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.
