When creating or modifying a resource or stonith, pcs should validate values of meta options when possible. For example clone-max, clone-node-max, master-max, master-node-max options can only have values of 0 or a positive integer.
Pcs should also validate names of meta options. For example setting clone-max on a primitive or remote-node on a clone has no effect. Meta options which have no effect for a given resource type (primitive, group, clone, master, bundle) should only be allowed with --force.
All the validations needs to be done in all commands which are capable of setting meta attributes:
* resource meta
* resource update
* resource create - primitive's meta and possible master's or clone's meta must be checked separately
* resource bundle create
* resource clone
* resource master
resource defaults should be validated as well
Option names are not validated currently and it is possible to set options with any name. This may be a valid use case so we need to carefully decide how to deal with unknown option names.
