[DPE-8337] Disable Patroni config to prevent possible data loss

[taurus-forever]

Port from PG14 #1173

Issue

In case of the split brain OR old primary cluster re-joining,
the special Patroni config options did re-silver the data,
potentially loosing the data on old-Primary unit (
as it cannot re-join current Primary due to timelines divergence).

The follow-up charm improvements are necessary to simplify re-init for user,
but for now let's disable dangerous Patroni options added in 29b8098.

Solution

Disable Patroni config options explicitly:
remove_data_directory_on_rewind_failure and
remove_data_directory_on_diverged_timelines.
They are disabled by default in Patroni.

Fixes 1153
