Not your fault, but this schedinfo command is a really dumb wrt
to option handling. Requiring that we add new options for every
possible schedular param for every possible hypervisor is just

Instead  of using a syntax

    schedinfo --weight 10

it should use

    schedinfo --set weight=10

so it automatically has support for every parameter supported
by the hypervisor in question. It can validate that the user
suplied param name is correct by calling 'virDomainGetSchedularParams'
to see what are available.

We need to implement a --set option, and deprecate use of the existing
--weight and --cap options in the help message/man page.
