Fix broken pep8 jobs due to bandit 1.7.5 updated version

With the latest version of bandit (1.7.5), a new lint rule has been
introduced that checks the inclusion of the timeout parameter for
every "requests" call [1].

So B113 lint rule[2] needs to be skipped or code adapted, this patch
add the timeout parameter to the put/get requests.
