To disable SSL by default we want to transfer OpenSSLDialer
and any other SSL logic to the new go-tlsdialer repository.

go-tlsdialer serves as an interlayer between go-tarantool and
go-openssl. All SSL logic from go-tarantool is moved to the
go-tlsdialer.

go-tlsdialer still uses tarantool connection, but also
types and methods from go-openssl. This way we are
removing the direct go-openssl dependency from go-tarantool,
without creating a tarantool dependency in go-openssl.

Moved all SSL code from go-tarantool, some test helpers.
