I guess that we need this in order to add index.mode: time_series in the indexes?
My only concern about this is that once again we move compatibility forward making it hard for bugfixes to land in the future. Not blocking though.

[jsoriano]

Yes, this was the concern I had about the approach of using the manifest elasticsearch settings.

[jsoriano]

Approach in this PR is not valid. It installs the index.mode setting in the @package component template, but in order to leverage elastic/elasticsearch#86790, it needs to be installed in the composable template. Started elastic/package-spec#357 to add a new setting in the spec for this.
