route /wopi to collaboration service

[butonic]

I am trying to run the collaboration service as easily as possible, but it does not work as expected when tryin to replace the approvider with it:

	"OCIS_ADD_RUN_SERVICES": "collaboration",
	"OCIS_EXCLUDE_RUN_SERVICES": "app-provider",
	"COLLABORATION_WOPIAPP_ADDR": "https://onlyoffice.ocis.test",
	"COLLABORATION_HTTP_ADDR": "https://cloud.ocis.test",
	"COLLABORATION_HTTP_SCHEME": "https",

I had to make the runtime recognize the collaboration service and start it, register proper service names and make the proxi route /wopi to the collaboration provider.

@butonic why now go through the proxy?

I was working under the assuption that we do not route wopi requests through the proxy.

How would you do that with 3 collaboration services?

I think "COLLABORATION_HTTP_ADDR": "wopiserver-collabora.ocis.test", should be the config.

[butonic]

We already learned that multiple collaboration services are only confusing end users. So IMO the default ocis setup should host one default /wopi endpoint. If you really really need additional wopi servers, only then will you need to set up a new (sub-)domain for it.

I think we sshould even default to "COLLABORATION_HTTP_ADDR": "https://localhost:9200", or well, OCIS_URL

hm ... I now see that the collaboration service uses the http addr differently than all other services ...
and it does not register the the grpc service in go micro (intentionally) ... I need to double check that works because the registry is still used to look up the service afaict ...

[butonic]

meh, the approvider part dies if it cannot connect to the wopi client to discover the urls ... urgh ... so we cannot start it by default ...

I'll first work on #9165 and then rebase this PR
