* Tests for JdbcResultSet
* Added VARCHAR conversion for different types
* Made error messages consistent: they now contain both the type that fails to be converted and the value itself
Significantly improve the example snippets in the documentation.
The examples are part of the test suite and checked nightly.
To help readability, the existing dataset was extended (test_emp renamed
to emp plus library).
Improve output of JDBC tests to be consistent with the CLI
Add lenient flag to JDBC asserts to allow type widening (a long is
equivalent to a integer as long as the value is the same).
Removes the last remaining server dependencies from jdbc client. In order to do that it introduces the new project sql-shared-proto that contains only XContent-serializable classes. HTTP Client and JDBC now depend only on sql-shared-proto. I had to keep the original sql-proto project since it is used as a dependency by sql-cli and security integration tests.

Removes dependency for server's version from the JDBC driver code. This
should allow us to dramatically reduce driver's size by removing the
server dependency from the driver.
