Will generate client certificates like these:

I've added preliminary support for remoteClients for an ESP component with externally facing services.

First step is to enable certificates, and the cert-manager issuer "remote".

certificates:
enabled: true
remote:
name: hpcc-remote-issuer

1.  

   1. set enabled to true if adding remoteClients for any components
      enabled: true

Then add the list of remote clients to the ESP.

This will:
1. Make that ESP require client certificates.
2. create a client certificate for each remoteClient. The certificates and private keys must be set up for the client.
3. Restricts access to the ESP to listed clients.

Future work may define other ways of adding or using client certificates.
