Can we also discuss the new JTL grammar? This is the current complete MDC
grammar of JTL:
```
config = singleAccess | multiAccess
singleAccess = key , [ stringified ]
key = "key" -> string
stringified = "stringified" -> boolean
multiAccess = [ pattern ] , [ replacement ] , [ flatten ] , [ stringified ]
pattern = "pattern" -> string
replacement = "replacement" -> string
flatten = "flatten" -> ( boolean | flattenConfig )
flattenConfig = [ flattenPrefix ]
flattenPrefix = "prefix" -> string
```
I'm not inclined to use `keyExcludes`, since it doesn't match the style used
for the `pattern` directive. What do you think of the following grammar
extension instead?
```
literal = [ literalAllowed ], [ literalDisallowed]
literalAllowed = "allowed" -> array of strings
literalDisallowed = "disallowed" -> array of strings
```
Example usage:
```
{
"$resolver": "mdc",
"pattern": "user:(role|rank)",
"replacement": "$1",
"literal": {
"allowed": [ "foo", "bar", "baz" ],
"disallowed": [ "do", "re", "mi" ]
}
}
```
Example usage for the case at hand:
```
{
"$resolver": "mdc",
"flatten": true,
"literal": {
"disallowed" -> [ "@timestamp", "message", "log.logger" ]
}
}
```
@ramanathan1504, @ppkarwasz, WDYT?
