This change modifies the file structure detection functionality such that some of the decisions can be overridden with user supplied values. The fields that can be overridden are: - charset - format - has_header_row - column_names - delimiter - quote - should_trim_fields - grok_pattern - timestamp_field - timestamp_format If an override makes finding the file structure impossible then the endpoint will return an exception.

nit: Excluding the first word the error message is duplicated and could be extracted.

| String quote = String.valueOf(csvPreference.getQuoteChar()); | ||
| String twoQuotes = quote + quote; | ||
| String optQuote = quote.replaceAll("([\\\\|()\\[\\]{}^$*?])", "\\\\$1") + "?"; |

This looks like you are escaping the set of regex special characters but some are missing. ., +, :?

I think : is OK as it's only special within contexts that won't arise if the other characters are escaped. But I'll add . and + and remove the duplication with the following line.
| FindFileStructureAction.Request request = new FindFileStructureAction.Request(); | ||
| request.setLinesToSample(restRequest.paramAsInt(FindFileStructureAction.Request.LINES_TO_SAMPLE.getPreferredName(), | ||
| FileStructureFinderManager.DEFAULT_IDEAL_SAMPLE_LINE_COUNT)); | ||
| request.setCharset(restRequest.param(FindFileStructureAction.Request.CHARSET.getPreferredName())); |

xpack.ml.find_file_structure.json should be updated with the new params and perhaps a yml test if possible
