[ENHANCEMENT] allow to set revisionHistoryLimit

[helmecke-nlb]

Describe the use case:

We are using ArgoCD and old replicaset only clutter the interface without any benefit. If we were able to set revisionHistoryLimit to "0" for deployments, replicasets without any pods would be removed.

Describe the enhancement/feature:

Add the following values to the values.yaml and render them into the corresponding Deployment spec.

connectors.revisionHistoryLimit: 10
console.revisionHistoryLimit: 10
identity.revisionHistoryLimit: 10
operate.revisionHistoryLimit: 10
optimize.revisionHistoryLimit: 10
tasklist.revisionHistoryLimit: 10
webModeler.restapi.revisionHistoryLimit: 10
webModeler.webapp.revisionHistoryLimit: 10
webModeler.websockets.revisionHistoryLimit: 10
zeebeGateway.revisionHistoryLimit: 10

Desired outcome and acceptance tests:

revisionHistoryLimit in every Deployment can be set via values.yaml.

@helmecke-nlb Thanks for the suggestion.
Currently, we are considering providing users a generic way to define any extra config they need.
Probably this will be part of the 8.6 release in October (maybe also before it).
