Improved TLS Support for Import/Export

COPY FROM VERTICA and EXPORT TO VERTICA can now require encryption of plan metadata during transmission. Previously, when making the connection using CONNECT, Vertica attempted to use TLS and fell back to plaintext for metadata. This is still the default behavior, but you can now require encryption and, optionally, require certificate validation by setting the ImportExportTLSMode configuration parameter.  For more information, see Configuring Connection Security Between Clusters in the Administrator's Guide.
