Add support connection using SSL

[LeonidVas]

The tarantool EE supports connection with SSL, but tt connect doesn't. It is necessary to add this functionality to tt connect.
The problem is that in this case we have to add the openssl dependency which will break the static build and we need to find a way to keep the static build if possible (maybe we need to add some changes to go-tarantool).
