When referring to the same ObjectStore with custom TLS certificates
multiple times, the plugin was adding the same volume projection two
times. This lead to a wrong Job definition.
This patch makes the plugin add a sidecar to replica cluster Pods that
are using the plugin to get WALs, even if the plugin itself is not used
for WAL archiving.
Closes: #329
