[COMMON] Enable importing custom certificates to truststore using certInitializer
ONAP deployments may require the use of custom certificates. Instead of manually adding certificates to the truststore file, users can now add their .pem certificates under certInitializer/resources and have them imported automatically by an init container. The updated truststore can then be mounted to a component by providing a truststoreMountpath. Issue-ID: OOM-2509 Signed-off-by: Jozsef Csongvai <jozsef.csongvai@bell.ca> Change-Id: I896c729143346738e91fa57f895ba48043b253c1
