Docker volume mounts fail after ending docker-run with <ctrl>-c

[thallgren]

Connecting using --docker and then doing an intercept using --docker-run which is terminated by -c, leaves the volume plugin in a bad state, causing a subsequent intercept to always fail to mount its volumes. Retrying the intercept succeeds though, because the failure takes the plugin out of the bad state. In summary, every other attempt to intercept will fail to mount its volumes.

The problem was addressed in this PR and made available in the 0.1.5 version of the plugin. Unless a workstation is air-gapped, this version is automatically detected and installed by the Telepresence client.
