[COMMON] Add prometheus service monitor template
Add prometheus service monitor template to common charts so that components can reuse it to enable scraping of their metrics by prometheus. Issue-ID: OOM-2710 Signed-off-by: Marat Salakhutdinov <marat.salakhutdinov@bell.ca> Change-Id: Ifa8da676dec05192c518ba97208df60e5ec46f55

+ Resolve the name of a chart's serviceMonitor.
+
+ The default will be the chart name (or $dot.Values.nameOverride if set).
+ And the use of .Values.metrics.serviceMonitor.name overrides all.
+
+ - .Values.metrics.serviceMonitor.name: override default serviceMonitor (ie. chart) name
+ Example values file addition:
+ metrics:
+ serviceMonitor:
+ enabled: true
+ port: blueprints-processor-http
+ ## specify target port if name is not given to the port in the service definition
+ ##
+ # targetPort: 8080
+ path: /metrics
+ basicAuth:
+ enabled: false
+ externalSecretName: mysecretname
+ externalSecretUserKey: login
