[DCAEGEN2] Updates for R10

By default, disable all dcaegen2 components except
config-binding-service, healthcheck,
and ves-openapi-manager.

Fix DNS name for the ONAP consul instance.

Move mongodb dependency from dcae-bootstrap to dcae-tcagen2.

Fix the generation of the JSON list of expected components for the
healthcheck services. (Previously could have a spurious leading
",")

Update healthcheck-container version to 2.3.0 for
logging enhancements and updated base image.

+  This template generates a JSON file with an array containing the names of the
+  components that the healthcheck container always expects to see--that is, the
+  components that are enabled in the top-level values.yaml file.
+
+  The code loops through the list of components ($components) and checks each component's
+  entry in the values.yaml file is set to "enabled".  It adds the name of each enabled
+  component to the list.
+
+  There is a bit of Helm trickery here--the code uses a dict ($enabled), because that's
+  apparently the only way to create a variable outside of a range loop that can be updated
+  from within the range loop.  The code here generates a list of the components that are
+  enabled in values.yaml, and stores it into the list called "enabled" in the dictionary
+  $enabled.
+
+  Note also the assignment to an otherwise unused variable ($x) in the loop.  Without that
+  assignment, the updated value of the $enabled.enabled list would be rendered into the
+  file each time an enabled component is found.
