Handle host and ssl internally #104
Description
Currently, we require a host and ssl as separate arguments for FlexMeasuresClient, something that we inherit from the HTTP library that we use internally.
As proposed by @Flix6x (see comment below), we should copy the util function get_host_and_ssl_from_url() (now part of our ha integration, here) to the main package and expose a single url argument for anybody using the client.
