Introduce common index with retries and move group handler

Indexing should be attempted multiple times, until the result is
validated by an UpToDateChecker, which will assess whether the entity
being indexed can now be considered up-to-date.

Because of that, all index handlers share the same structure, they all
need a way of checking whether data is up-to-date, they all need a
scheduler to retry, they all need to read the same [index]
configuration.

Create a base class for index handler and start by moving group index
handler to use it.

Subsequent changes will address other index handlers.
