orahost: added options to host_fs_layout

[Rendanic]

The host_fs_layout could be used to changed filesystems from OS itself.

Important:
Always set the owner, group and mode for filesystems, because the
defaults are oracle:oinstall and 0775.

Example:

host_fs_layout:
  - vgname: rootvg
    state: present
    filesystem:
      - {mntp: /tmp, lvname: tmplv, lvsize: 1200m, fstype: ext4, owner: root, group: root, mode: 1777}
    disk:
      - {device: /dev/sda, pvname: /dev/sda2}
