cli: ensure the program returns 0 on success and 1 on error

propagate a returncode in each operation and make it the
returncode of the program.

Prevent sys.exit calls in post(), get() and delete() request
handlers to enable cleanup code and error handling. Keep a basic
error log inside the request functions if the connection can't
be established or if the response contains an error code.
