> External + purge tables are more backward compatible with the old managed tables.
> Applications can use a HS2 URL that sets the session level property for default table type to external-purge tables to be true.
> As part of this we need a notion of a "session level only" config parameter(s).
> Adding a new jdbc config: *hiveCreateAsExternalLegacy*, a hs2 config *hive.create.as.external.legacy*, when set to true, create external purge table by default.
> Adding *MANAGED* keyword. "create managed table" will create table based on hive.create.as.acid and hive.craete.as.insert.only values, not impacted by the new config.
