ReportPortal.config.schema still has 'authentication' as required property of server

[schrufygroovy]

See: https://github.com/reportportal/agent-net-vstest/blob/master/src/ReportPortal.VSTest.TestLogger/ReportPortal.config.schema

I think the authentication should no longer be in the list of required properties, because now it can be configured via apiKey.

@nvborisenko , could you please take a look into this request?

[nvborisenko]

The request is correct, all properties in json should not be required, because json is not singe source of configuration.
