If docker is enabled, start mesos-slave.service after docker.service
to avoid a race condition that could result in mesos-slave to fail
with "Failed to create docker: Timed out getting docker version"
The working directory needs the x flag, otherwise executors (e.g. sparks executor) are unable to cd into their sandbox and create e.g. temporary files.
- Usage of docker containerizer is currently hardcoded, this PR makes it
optional. Default is to enable it if docker is enabled.
- Make IP address to listen on part of service configuration.
Added attributes to nixos/tests/mesos.nix to verify that mesos-slave
attributes work. If the generated attributes are invalid, the daemon
should fail to start.
