[#77] TLS Test

Dockerfile

• Install YDBEncrypt
• Remove use of LD_LIBRARY_PATH
• Remove ydb_env_set completely, as we now actively avoid it to ensure no global mode
• Creat TLS certs, and include new ydb_crypt_config file ci/ydbgui.ydbcrypt

ci/run_test.sh

• Set USER, as it's required by maskpass utility
• Setup TLS password
• Add new modes "server_tls" and "debug_tls" for testing/debugging TLS
