Release v0.8.6

Improvements

• [jdbc-v2] Now using Antlr4 to parse SQL statements to get meta information about it.
  Invalid SQL still possible to execute if logic able to get all required information. (#2351)
• [jdbc-v2] Now possible to use RowBinaryWriter if enabled by property com.clickhouse.jdbc.internal.DriverProperties.BETA_ROW_BINARY_WRITER.
  This works well for batches. Single statements may get no benefits. (#2316)

Bug Fixes

• [jdbc-v2] Fixed parsing prepared statement arguments. (#2348)
• [jdbc-v2] Fixed parsing role name when it contains -. (#2325)
• [jdbc-v2] Fixed failure when INSERT doesn't contain VALUES. (#2283)
• [jdbc-v2] Fixed parsing INSERT statement when VALUES is in lower case. (#2354)
• [client-v2] Fixed NPE when async operation is request while client was built without an executor.
  In this case default JVM executor will be used. (#2355)
• [client-v2, jdbc-v2] Fixed conversion of IP addresses. When IPv4 stored as IPv6 it is correctly converted
  to Inet6Address. Similar problem fixed for JDBC. (#2342)
• [jdbc-v2] Fixed changing DB schema (DB name) on connection when USE statement executed. (#2137)
• [client-v2] Fixed serializing POJO with primitive boolean fields. (#2248)
