Alex Dadgar 14ed757a56 Plugins use parent loggers
This PR fixes various instances of plugins being launched without using
the parent loggers. This meant that logs would not all go to the same
output, break formatting etc.

// This package provides a mechanism to build the Docker driver plugin as an
// external binary. The binary has two entry points; the docker driver and the
// docker plugin's logging child binary. An example of using this is `go build
// -o </nomad/plugin/dir/docker`. When Nomad agent is then launched, the
// external docker plugin will be used.
