Unable to start two workspaces with a specified service endpoint

[sympatheticmoose]

Describe the bug

When trying out the intellij devfile - https://raw.githubusercontent.com/redhat-developer/codeready-workspaces/crw-2.5-rhel-8/dependencies/che-editor-intellij-community/devfiles/meta.yaml

it includes this:

spec:
  endpoints:
   -  name: "intellij"

As such the first workspace created will create a Intellij service, but trying to create a second will cause a fatal error with the following message:
Error: Failed to run the workspace: "Failure executing: POST at: https://172.30.0.1/api/v1/namespaces/openshift-workspaces/services. Message: services "intellij" already exists. Received status: Status(apiVersion=v1, code=409, details=StatusDetails(causes=[], group=null, kind=services, name=intellij, retryAfterSeconds=null, uid=null, additionalProperties={}), kind=Status, message=services "intellij" already exists, metadata=ListMeta(_continue=null, remainingItemCount=null, resourceVersion=null, selfLink=null, additionalProperties={}), reason=AlreadyExists, status=Failure, additionalProperties={})."

Has been seen in CRW 2.5 on OCP 4.6 and che.openshift.io

The difference between IntelliJ and Che Theia endpoints is that Che Theia one has the following attributes:

        secure: true
        cookiesAuthEnabled: true
        discoverable: false

So, may be related.

not sure what are the default values if the attributes are omitted

[azatsarynnyy]

@metlos suggested in the chat to define discoverable: false explicitly
as the plugin endpoints are discoverable by default

I've sent a PR to fix the plugin descriptor file upstream eclipse-che/che-plugin-registry#691
