* Add optional logical backup retention time
* Set defaults for potentially unbound variables, so that the script will work with older operator versions
* Document retention time parameter for logical backups
* Add retention time parameter to resources and charts

* restart master first in some edge cases
* edge case is when desired is lower than effective
* wait after config patch and restart on sync whenever we see pending_restart
* convert options to int to check decrease and add unit test
* minor update to e2e tests
* wait only after restart not every sync
* using spilo 14 e2e images
* bump tp v1.6.0
* update logical-backup image
* Using smaller image for e2e test.
* fix env var name in docs
* add postgresql-client-13 to logical backup image

Connection pooler support
Add support for a connection pooler. The idea is to make it generic enough to
be able to switch between different implementations (e.g. pgbouncer or
odyssey). Operator needs to create a deployment with pooler and a service for
it to access.
For connection pool to work properly, a database needs to be prepared by
operator, namely a separate user have to be created with an access to an
installed lookup function (to fetch credential for other users).
This setups is supposed to be used only by robot/application users. Usually a
connection pool implementation is more CPU bounded, so it makes sense to create
several pods for connection pool with more emphasize on cpu resources. At the
moment there are no special affinity or tolerations assigned to bring those
pods closer to the database. For availability purposes minimal number of
connection pool pods is 2, ideally they have to be distributed between
different nodes/AZ, but it's not enforced in the operator itself. Available
configuration supposed to be ergonomic and in the normal case require minimum
changes to a manifest to enable connection pool. To have more control over the
configuration and functionality on the pool side one can customize the
corresponding docker image.

* Added possibility to add custom annotations to LoadBalancer service.
* Added parameters for custom endpoint, access and secret key for logical backup.
* Modified dump.sh so it knows how to handle new features. Configurable S3 SSE
You can specify an environment variable DEBUG 1/0 to enable/disable
debug mode. Debug mode assumes delve dependency for remote debugging,
and debugging symbols for go build.
introduce Pod events channel;
add parsing of the MaintenanceWindows section;
skip deleting Etcd key on cluster delete;
use external etcd host;
watch for tpr/pods in the namespace of the operator pod only;
