What happened?

When using a custom VPN like new SolaceContainer("solace/solace-pubsub-standard:10.11.1.147").withVpn("myVpn") some permissions (capabilities?) seem to be missing, as one can no longer

provision queues
create flows
(and maybe more)

Running the same code omitting .withVpn("myVpn") works just fine.

Relevant log output

Stacktrace when provisioning:

com.solacesystems.jcsmp.AccessDeniedException: Permission Not Allowed
	at com.solacesystems.jcsmp.impl.SessionModeSupport.provision(SessionModeSupport.java:734)

Stacktrace when creating flows:

com.solacesystems.jcsmp.InvalidOperationException: Capability Mismatch: Router does not support guaranteed subscriber flows.

Additional Information

Using image versions 10.8, 10.8.1.152 or latest (i.e. 10.11.1.167) yield the same results.
