external volumes should accept absolute containerPath

[vixns]

according to http://mesos.apache.org/documentation/latest/docker-volume/, containerPath can be absolute or relative.

Marathon implementation does not accept absolute paths yet, please remove https://github.com/mesosphere/marathon/blob/releases/1.2/src/main/scala/mesosphere/marathon/core/externalvolume/impl/providers/DVDIProvider.scala#L162

Maybe @jdef can add his opinion to this issue :)

Saw your TODO here https://github.com/mesosphere/marathon/blob/releases/1.2/src/main/scala/mesosphere/marathon/core/externalvolume/impl/providers/DVDIProvider.scala#L168

via @Gilbert88

we have it included in [mesos] 1.0
so in the future, only command task (mesos container without image specified) case has to use the relative container_path.
for docker container or mesos container with image specified, container_path can be either absolute or relative.
