pengine: Allow use of resource params and meta-params in location rules
This would allow following syntax:
<rule id="resource-require-home-zone-rule" score="-INFINITY" boolean-op="or">
<expression id="resource-require-home-zone-expr-0" attribute="node-zone" operation="not_defined" /> <expression id="resource-require-home-zone-expr-1" attribute="node-zone" operation="ne" value="resource-zone" value-source="meta" />
</rule>
Suggested syntax in crmsh terms:
location resource-require-home-zone /resource-.+/ \
rule -inf: not_defined node-zone or node-zone ne meta{resource-zone}
