# usage: ynh_local_curl "page_uri" "key1=value1" "key2=value2" ...
# | arg: page_uri    - Path (relative to $path_url) of the page where POST data will be sent
# | arg: key1=value1 - (Optionnal) POST key and corresponding value
# | arg: key2=value2 - (Optionnal) Another POST key and corresponding value
# | arg: ...         - (Optionnal) More POST keys and values
