Extend POSSIBLE_QUERY_OPTIONS in PinotConnection to all query level options

[chrajeshbabu]

Currently Query options can set to Pinot connection are just null handling and multi stage engine but there are many options like timeout, usestartree etc which can be allowed to configure so extend below list to all available options.

protected static final String[] POSSIBLE_QUERY_OPTIONS = { QueryOptionKey.ENABLE_NULL_HANDLING, QueryOptionKey.USE_MULTISTAGE_ENGINE };

for (String possibleQueryOption: POSSIBLE_QUERY_OPTIONS) { Object property = properties.getProperty(possibleQueryOption); if (property != null) { _queryOptions.put(possibleQueryOption, parseOptionValue(property)); } }
