cookie manipulation issues #511

I have a situation where I want to extract the cookies from a response, parse them, and then use them as input to a separate response. Trying to use hackney_cookie:parse_cookie and hackney_cookie:setcookie resulted in some inconsistencies:

• parse_cookie parses all parameters while setcookie only accepts a subset of options and drops the rest
• parse_cookie returns binary keys while setcookie expects atoms
• parse_cookie returns Max-Age as a string, while setcookie expects an integer
