Major rework of the extension. PoWA 2 is now only compatible with PostgreSQL

[pg_stat_kcache](https://github.com/dalibo/pg_stat_kcache). Third-part
extensions can also now be implemented easily.

The UI is also now in a [new repository](https://github.com/dalibo/powa-web),
with more frequent release cycle.
