RAMWeigher and CPUWeigher docs don't link properly to config options

[Matt Riedemann]

I don't know why the sphinx build doesn't fail for this, but the oslo config option links for the RAMWeigher and CPUWeigher don't work:

https://docs.openstack.org/nova/latest/user/filter-scheduler.html#weights

RAMWeigher Compute weight based on available RAM on the compute node. Sort with the largest weight winning. If the multiplier, :oslo.config:opt:`filter_scheduler.ram_weight_multiplier`, is negative, the host with least RAM available will win (useful for stacking hosts, instead of spreading).

CPUWeigher Compute weight based on available vCPUs on the compute node. Sort with the largest weight winning. If the multiplier, :oslo.config:opt:`filter_scheduler.cpu_weight_multiplier`, is negative, the host with least CPUs available will win (useful for stacking hosts, instead of spreading).

===

Those should be using ":oslo.config:option:".

    Fix tox -e docs

    This was missed in I90ee8a2081c2a0465441a8d81d161f4887b4e1fb
    presumably because we no longer get warnings as errors, or
    some such wickedness. Anyway, this fixes docs build using tox.
