[RFE] Allow using values from introspection for rule conditions

[Carmelo Ragusa]

Currently it is possible to fetch values from the introspection data and assign it to a rule action, but it is not possible to fetch a value from introspection and use it as a rule condition.

For example as a condition:
If the bmc in the introspection data is equal to the ipmi address in the driver info of the node (for the condition), then set the ipmi username and password (as credentials).

Or:
Assign a different kernel and ramdisk based on the amount of RAM

I am not sure this is A true issue. I used Collected data in rule conditions since Mitaka version of inspector. I have used it to do what describe. I assign ipmi credentials based on manufacturer.
As an example:
{"op": "contains", "field": "data://inventory.system_vendor.manufacturer", "value": "Dell"}
or
{"op": "contains", "field": "data://inventory.system_vendor.manufacturer", "value": "HP"}

it is worth noting that I carry a patch internally to collect system_vendor information, but no code change to anything around the conditional usage support.
