Add configurable SSL options

[zediogoviana]

Why:

• Add the possibility of configuring SSL options if the user chooses to.

How:

• Check if the connection type is :ssl (by specifying true to keep retro-compatibility or by specifying a keyword list).
• If a list is passed, it merges the default options with the ones given by the user.
• If no options are passed or the connection is not :ssl the default list is used.

@florinpatrascu when you have the time, could you have a look at this?

Hi and I apologize that I don't have time to respond at length to the PRs. First of all I want to thank you for this improvement. Then about the PR. Don't you think it would be better if we keep one parameter: ssl, converted to a list (of options). A list of options, can be the equivalent to ssl: true?! What do you think?

Thanks for the reply, and for your time on this project! Yes, I agree with you! It seems to be a cleaner solution. I'll update the PR 👍

@florinpatrascu what do you think now? It should keep working if someone just passes true, for retro-compatibility and also for the ones that don't want to specify any custom option.
