Added Solaris support to core mount module (#4771)

* Added Solaris support to the mount module.

* Added checking so that if a non-standard fstab file is specified it will
still work in Solaris without breaking existing functionality.

* Added a check to avoid writing duplicate vfstab entries on Solaris

* Added "version_added" to new boot option
