Changes to add A records of source and registry as metrics. The existing metrics -
external_dns_registry_endpoints_total & external_dns_source_endpoints_total gives a cumulative count of records all records (A, SRV, CNAME, TXT).

We have a metric - external_dns_controller_verified_records which gives the intersection of A records between source & regsitry. However, in order to determined how many records are yet to be synced to registry, we need count of total A records in registry & source.

Only add cluster role permissions for enabled sources

Add Istio permissions to cluster role

service: fix merging of endpoints - same hostname different set-identifier

In OCP when you have multiple ingress controllers the route's status Ingress object get populated with multiple router canonical names. So in this case, the external dns tries to add multiple CNAME records for same host in the same hosted zone which is a violation of RFC 1912  and therefore is rejected by standards-compliant DNS services.

This feature adds a router field to the OCP Route Source so that a user can add an ingress controller name in flag --ocp-router-name which will be used to pick up the respective routerCanonicalHostname from Route's Status Ingress Object.
