Not able to enable https for AwsAuthV4 transport

[cfoehrdes]

We are trying to use the AwsAuthV4 transport with ssl and are not able to pass the ssl option to it.

It seems that it is not possible because the ssl config param accessed in the AwsAuthV4 class (see https://github.com/ruflin/Elastica/blob/master/lib/Elastica/Transport/AwsAuthV4.php#L77) is never set.
The keys of the config array are limited to bigintConversion, curl, headers and url in the client when preparing the transport configuration. (see https://github.com/ruflin/Elastica/blob/master/lib/Elastica/Client.php#L162)

It could be an option to pass the ssl key to the config array or maybe we could also use getParam to fetch the ssl setting, as it is done with the access keys.

@cfoehrdes Feel free to open a PR for further discussions. This should make it more obvious what the changes required would be.

@ruflin The PR #1457 is pretty much what solves the problem

Closing as #1457 was merged.
