Release 2.0.0-rc29 (#236)

## What does this PR do ?

This release is a **major** rewrite of the plugin architecture, API and data model.

The version is supposed to be very close of the final 2.0.0 stable version of the plugin. Very few breaking changes are expected until final release.

Migration scripts may be provided as we are going forward this huge step.

The documentation will be entirely rewritten when the 2.0.0 is release.
