fix: use the [] after key names for array variablesjlvillal/arrays

1. Create a new CommaSeparatedListAttribute class. This is to indicate
   types which are sent to the GitLab server as
   comma-separated-strings (CSV) but we have been allowing users to
   use a list-of-strings.  These values are NOT array values, so
   adding [] to the key name breaks them.

2. Rename ListAttribute to ArrayAttribute.

3. If a value is of type ArrayAttribute then append '[]' to the name
   of the value.

4. Move processing of most GitlabAttributes into the
   client.py:http_request() method. Now we convert our params into a
   list of tuples so that we can have multiple identical keys but with
   different values.

Fixes: #1698
