NIFI-5826 Fix to escaped backslash
Fixing escaped backslash by unescaping it in java just before compiling
regex.
-----
For a consistency with expression language regex-based evaluators, all
record path operators will follow the same escape sequence for regex. Single
backslash should be defined as double backslash.
Examples:
- replaceRegex(/col1, '\\s', "_") - will replace all whitespaces (spaces,
tabs) with underscore.
- replaceRegex(/col1, '\\.', ",") - will replace all a period with
- replaceRegex(/col1, '\\\\', "/") - will replace backslash with forward
slash
