@cgivre @vvysotskyi before I come and fix the unit test failures here, what
is a good road forward as far as security goes?
1. Make this feature disabled by default with a boot option for enabling it
and add a warning about arbitrary command execution.
2. Decide that users and applications that want to run mount commands must
handle that themselves externally and close this PR.

> This Jira proposes optional mount and unmount commands in the filesystem
> plugin with the goal of enabling the dynamic definition of filesystem mounts
> in the storage configuration. It is mainly anticpiated that network and cloud
> filesystems that have FUSE drivers (sshfs, davfs, rclone, ...) will be used
> in this way but local device mounts and image/loop device mounts (ISO, IMG,
> squashfs, etc.) might also be of interest. Filesystems that can be mounted in
> this way become queryable by Drill cluster without burden of dedicated
> storage plugin development.
> The provided commands are executed in their own processes by the host OS and
> run under the OS user that is running the Drill JVM. The mount command will
> be executed when an enabled plugin is initialised (something that is done
> lazily) and whenever it transitions from disabled to enabled. The provided
> unmount command will be executed whenever a plugin transitions from enabled
> to disabled and when the Drillbit shuts down while the plugin has been
> initialised and is enabled.
> Example using udisks on Linux to mount and unmount an image of an ext4
> filesystem.
