## drilldown_uri:     Specifies a custom target for viewing the events
##                    outputted as a result of the action.
##                    Custom target can specify app and/or view depending on syntax.
##                    Optional.
##                    For instance, "my_view?form.orig_sid=$sid$&form.orig_rid=$rid$"
##                    For instance, "../my_app/my_view?form.orig_sid=$sid$&form.orig_rid=$rid$"
## field_name_params: The param or params which represent the name of a result field.
##                    Optional.
##                    For instance, ["param.search_field"] indicates that the value of "param.search_field"
##                    should be present as a field in the result or results being operated on.
## required_params:   Parameter(s) required for successful action execution. 
##                    Indicated by "*" in the custom alert action user interface. 
##                    For instance, ["param.search_field"] indicates that "param.search_field"
##                    should be specified when submitting the action on the custom alert action
##                    user interface.
##                    Optional.
## supports_adhoc:    Specifies if the modular action supports adhoc invocations.
##                    Optional.
##                    Defaults to False.
## supports_cloud:    Specifies if the modular actions supports the "cloud" model.
##                    For instance, does the action function properly when the search head does not have access
##                    to the local network.
##                    Optional.
##                    Defaults to True.
