oCIS server in app-provider CI pipeline can exit sometimes (ocis using MICRO_REGISTRY=mdns)

Descritpion

The login step for the pipeline in the web-master is being flaky. Need some investigation why it is being flaky.

On UI it is stucked at while login:

[SwikritiT]

this is a server related issue which is reported here owncloud/ocis#7279

[saw-jan]

e2e fails when the created user wants to login. Looks like admin user can login and do requests during the test

currently, ocis exists at service so started to fail at wait -for-ocis.

It happens with ocis when using MICRO_REGISTRY=mdns (and we need mdns for app-provider tests). So can't do anything from our side.

Checked in #9767.

[kobergj]

Needs nats micro registry. Followed by this ticket: owncloud/ocis#7296
