      Description of problem:

      There are no error checks or warnings when setting invalid resource meta attributes. This can lead to unexpected behaviors for users who believed they set a valid option.

      Version-Release number of selected component (if applicable):

      $ rpm -q pcs
      pcs-0.10.8-1.el8.x86_64

      How reproducible:

      Set an invalid meta attribute to either a specific resource or for resource defaults:

       

      [root@clusterb-rhel8 ~]# pcs resource defaults update resource-sti=1000
Warning: Defaults do not apply to resources which override them with their own defined values
[root@clusterb-rhel8 ~]# pcs resource update dummy1 meta resource-sti=100

       

      Actual results:

      This results in an update to the configuration, but the values won't actually do anything since the attribute are invalid:

      [root@clusterb-rhel8 ~]# pcs config
---------------->8--------------------
Resources:
Resource: dummy1 (class=ocf provider=heartbeat type=Dummy)
Attributes: fake=1
Meta Attrs: resource-sti=100
---------------->8--------------------
Resources Defaults:
Meta Attrs: rsc_defaults-meta_attributes
resource-sti=1000
resource-stickiness=1000

      Expected results:

      A warning or error that prevents an update to configuration, and requests additional "--force" option to set invalid values.
