Add ReplaceStringProcessor for simple string substitution that doesn't involve regex

[dinujoh]

Is your feature request related to a problem? Please describe.
It would be nice to have ReplaceStringProcessor that use Java String.replace() method that is highly optimized for simple string replacements. It uses a more efficient algorithm than the Matcher.replaceAll() method used in SubstituteStringProcessor

Describe the solution you'd like
ReplaceStringProcessor implementation

final String newValue = value.replace(entry.getFrom(), entry.getTo());
recordEvent.put(entry.getSource(), newValue);
