The _do_call method needs a check for application/zip content

[sbarbett]

When you send a batch zone export request and retrieve the task, the result is a zip file. The connection module has no logic for handling application/zip content, so it tries to serialize it as though it were JSON.

There was an issue with the variable name in the connection module (I copied and pasted it from my own module and forgot to rename "resp" to "r1"). However, this will not pass the pull request workflow because it looks like the hostname variable is undefined in the repository secrets:

requests.exceptions.InvalidURL: Invalid URL 'https:///v1/authorization/token': No host supplied

@stevedejong if you refer back to #14 - It looks like this is the same issue

I added a few more lines of code to address some nuances with parsing the responses from certain APIs. For instance:

There are APIs that will return a 202 (ACCEPTED) response, but will not have an x-task-id header. Once such API is /v1/zones/{zone_name}/healthchecks. Instead, there is a location header which contains the URI of the result.

There are also APIs which do not have a 'content-type' header in the response, such as /v1/zones/{zone_name}/snapshot
