OPAL case sensitive filtering with match_regex

OPAL filters are case-insensitive by default. Case sensitive filtering is used when the filter verb is combined with the match_regex function.

match_regex

Use the filter verb’s support for OPAL functions to call match_regex, which can use the case insensitivity regular expression flag. log: 2024-04-06T12:49:00Z,eventName=GetPolicy
