Allow configuration of patroni's replication mode (#869)

Browse Source 
* Add patroni parameters for `synchronous_mode`

* Update complete-postgres-manifest.yaml, removed quotation marks

* Update k8sres_test.go, adjust result for `Patroni configured`

* Update k8sres_test.go, adjust result for `Patroni configured`

* Update complete-postgres-manifest.yaml, set synchronous mode to false in this example

* Update pkg/cluster/k8sres.go

Does the same but is shorter. So we fix that it if you like.

* Update docs/reference/cluster_manifest.md

Co-Authored-By: Felix Kunde <felix-kunde@gmx.de>

* Add patroni's `synchronous_mode_strict`

* Extend `TestGenerateSpiloConfig` with `SynchronousModeStrict`
