Add parameter IronicIPXEUefiSnpOnly

Add new parameter IronicIPXEUefiSnpOnly (default: true).
When `true` ipxe-snponly.efi is used for UEFI, when `false` ipxe.efi
is used.

'snponly.efi' is the default in puppet-ironic master branch, however
in Wallaby and earlier releases 'ipxe.efi' is the default. Since
'ipxe.efi' is not compatible with a lot of hardware TripleO should
change this default.

+    The default UEFI iPXE bootfile is now `snponly.efi`. The boolean parameter
