assembly descriptors should be optional

[tdiesler]

The target image may just want to set a few env entries or a different command

[ERROR] Failed to execute goal org.jolokia:docker-maven-plugin:0.10.4:build (build-docker-image) on project wildfly-camel-itests-openshift-domain: Error reading assembly: No assembly descriptors found. -> [Help 1]

thx, will have a look ASAP.

this should be able to handled as part of #64 however i think it will required an explicit setting to indicate no assembly required b/c if you were ok w/ all the defaults, you wouldn't need to define an assembly block and would just need to make sure you had a file in the default directory (currently src/main/docker however that can also be changed).

it looks like i forget to do this w/ #64 but i just submitted a pull request for this.

fixed in 0.11.2
