[Fleet] Add install_format_version to package and reinstall on setup

[nchaulet]

Summary

Resolve #121099

That PR allow to reinstall packages and related es assets, like index template, ... when we made a change on how we install them in Fleet.

To do so I added a new install_format_version on the package saved object and on setup if that version is less than the current version we reinstall packages.

This is covered by an integration test.

Saved Objects .kibana field count

Every field in each saved object type adds overhead to Elasticsearch. Kibana needs to keep the total field count below Elasticsearch's default limit of 1000 fields. Only specify field mappings for the fields you wish to search on or query. See https://www.elastic.co/guide/en/kibana/master/development-plugin-saved-objects.html#_mappings
