OPAL case-sensitive filtering with equals

OPAL filters are case-insensitive by default. Case-sensitive filtering is used with the filter = operator and a quoted string.

Given the following string:

log: 2024-04-06T12:49:00Z,eventName=GetPolicy

The following example uses the = operator and a quoted string to force a case-sensitive match with that string.

filter eventName="GetPolicy" //matches
filter eventName="getpolicy" //does not match
