Add custom annotations to deployment

[alen-z]

Add ability to add custom annotations to deployment, e.g. sidecar.istio.io/inject: "false" would be valuable if deployed in namespace where sidecar injection is enabled. CSR deployment shouldn't have a sidecar.

In an another issue : cert-manager/cert-manager#4646 (comment) it's mentioned to add in podlabels, but it's showing error realed to Helm. Using v1.12.3

No custom labels can be added.

Deployment:

istio-csr/deploy/charts/istio-csr/templates/deployment.yaml

Lines 6 to 7 in d6908d9

	labels:
	{{ include "cert-manager-istio-csr.labels" . | indent 4 }}

Template:

istio-csr/deploy/charts/istio-csr/templates/_helpers.tpl

Lines 19 to 27 in d6908d9

	{{- define "cert-manager-istio-csr.labels" -}}
	app.kubernetes.io/name: {{ include "cert-manager-istio-csr.name" . }}
	helm.sh/chart: {{ include "cert-manager-istio-csr.chart" . }}
	app.kubernetes.io/instance: {{ .Release.Name }}
	{{- if .Chart.AppVersion }}
	app.kubernetes.io/version: {{ .Chart.AppVersion | quote }}
	{{- end }}
	app.kubernetes.io/managed-by: {{ .Release.Service }}
	{{- end -}}

Another use case is adding annotations for prometheus scrape jobs. Now only scraping via service is possible which is not acceptable for everyone
