Add support for XCP-ng

[anothermerge]

Please update the params.pp to add XCP-ng to the list for RedHat systems. I think like 58.

Change this:
'RedHat','CentOS','Fedora','Amazon','Scientific','OracleLinux', 'AlmaLinux', 'Rocky', 'OpenSuSE', 'SLES' : {

to this:
'RedHat','CentOS','Fedora','Amazon','Scientific','OracleLinux', 'AlmaLinux', 'Rocky', 'OpenSuSE', 'SLES', 'XCP-ng' : {

Thanks

Oh, also init.pp lines 469 and 790.
