I would like a simple way to trim whitespace from an attribute
Describe the solution you'd like
I would like to be able to trim data from an existing attribute
For example
A field test exists in an event, which contains the string " this is a test ".
I would like to be able to transform this using an ottl function trim, that I would define as trim(attribute["test"]), which would trim this down to "this is a test".
By default, this would use the unicode definition of whitespace, but we would also allow an alternative version trim(attribute, symbols)
I would also like to be able to set my own definition of whitespace, by providing a string containing the symbols I would like to trim.
Describe alternatives you've considered
A user could do this using the existing replace_all_patterns function, but this is a common enough function that it may warrant a standalone function. Additionally, we can be unambiguous that we replace the Unicode definition of whitespace by default.
