conf: Introduce virDomainDefCputuneValidate helper

Browse Source 
Introduce a simple validation helper to perform the cputune period and
quota checks so that we can get rid of those repetitive chunks. Since
this is a validation helper, this patch also moves the checks from the
'parse' phase into the 'validation' phase.
