monitor: introduce query-command-line-options
Libvirt has no way to probe if an option or property is supported, This patch introduces a new qmp command to query command line option information. hmp command isn't added because it's not needed.

+ or 'size')
+ - "help": human readable description of the parameter
+ (json-string, optional)
+
+Example:
+
+-> { "execute": "query-command-line-options", "arguments": { "option": "option-rom" } }
+<- { "return": [
+ {
+ "parameters": [
+ {
+ "name": "romfile",
+ "type": "string"
+ },
+ {
+ "name": "bootindex",
