Check if mount point already exists

Typically, we create the mount point directory when we mount the
filesystem, and then we remove the directory when we unmount. Currently,
we aren't accounting for the case where the directory already exists,
e.g. if the BMC reboots while the filesystem is mounted.

This commit adds a check to see if the directory is already present. If
so, it won't try to create the directory again.

Tested:
1. Formatted an eMMC using the FormatLuks method, which also creates the
mount point and mounts the filesystem.
2. Rebooted the BMC
3. Ran the Unlock method to unlock the LUKS device and mount the
filesystem.

Switch to new D-Bus interface

Now that the eStoraged interface is in phosphor-dbus-interfaces, we can
remove the yaml files from this repo and switch to the new interface in
phosphor-dbus-interfaces. Note that the new interface is slightly
different. Some functions have different arguments, and the
eStoraged-specific errors were removed.

Also, the new interface allows for the caller to specify the filesystem
type, but for now, only ext4 is supported.

Format LUKS encrypted device

This commit adds the functionality to format a new LUKS device, create a
filesystem, and mount it. Unit tests are included.

Currently, the D-Bus interface to format the LUKS device is synchronous,
but it may need to become asynchronous, since it can take some time. The
format operation took about 20 seconds when testing it.

Tested: Ran eStoraged on a machine with an eMMC, using the following
commands:
$ /usr/bin/eStoraged -b /dev/mmcblk0 &
