Use elasticsearch-operator for ES deployment

[pavolloffay]

We would like to use https://github.com/openshift/elasticsearch-operator to manage ES deployment. This should be optional and users can still bring managed ES instances. The elasticsearch-operator uses this ES image https://github.com/openshift/origin-aggregated-logging/tree/master/elasticsearch.

There are a couple of problems with the eslasticsearch-operator. It's openshift-common-logging specific (uses their image), however we will make it more generic to be used with any APP and vanilla ES image.

The following steps are required to make the es-operator work with jaeger operator:

• Allow es-operator to watch every namespace Updating es manifest to allow it to watch all namespaces openshift/elasticsearch-operator#74
• add searchguard rules to ECL Elasticsearch image https://github.com/openshift/origin-aggregated-logging/pull/1500/files
• create Role and RoleBinding when es-operator is being used (follow openshift-ansible/roles/openshift_logging_elasticsearch/templates/loggin-jaeger-rolebinding.ym)
• create certificates https://github.com/openshift/cluster-logging-operator/blob/master/scripts/cert_generation.sh
• OLM deploys es-operator and jaeger operator, jaeger operator just creates es CR
• pass /var/run/secrets/kubernetes.io/serviceaccount/token bearer token to jaeger (it's my service accout)
• mount certificates to jaeger

• Add ES to OLM catalog https://github.com/jaegertracing/jaeger-operator/tree/master/deploy/olm-catalog
