DRILL-4452: Uses Apache Calcite Avatica driver vs Optiq driver for Drill JDBC
Drill JDBC driver uses Optiq Avatica as its basis, but this dependency has
been moved over to Calcite, for quite some time without Drill code being
updated for it.
This patch updates Avatica version to the version from Calcite
(1.4.0-drill-r19). It also refactors Drill JDBC driver to comply with the
packages and API changes in Avatica. Finally it fixes the the SQL types for
lists and structs, since Drill doesn't support java.sql.Array and
java.sql.Struct interfaces.
this closes #395
