Create a CoverageReader for remote WMTS layers


A WMTS CoverageReader would allow GeoServer to publish cascading WMTS layers.

A draft working implementation foresee:

New modules:

Modified modules:

!!! Since the related changes in GeoServer cannot be enclosed in a single community module but need changes in the ``main`` and other core modules, the needed GeoTools classes should be promoted out from the ``unsupported`` status.

I pushed some new commits that:

  • move the tile-client module into extensions

  • move the wmts module into extensions

  • update file headers

  • add some tests (code coverage for both tile-client and wmts is over 60%)

  • clean up code

Hi Everyone,

I discovered GeoTools some month ago with many expectations about WMTS.
I will be happy to test these new feature.

I'm prepared to volunteer to be a joint maintainer on these modules.

Dear Emanuele,
I guess at this point you can move forward.

You are implicitly volunteering to become the maintainer of the
modules which are going to be moved from unsupported to supported,
i.e. tile-client.
Are you happy with that?

Hi list,

any comment on this proposal?

Shall I open a separate ticket for the graduation of the tile-client module?
