tox -e docs fails due to faulty api sample

[Balazs Gibizer]

tox -e docs fails on master (df8216b2bcf3657b1c89797d4e3ecc456cf27054) with

python -m json.tool doc/api_samples/servers/v2.19/server-put-req.json
Expecting property name: line 5 column 5 (char 117)
ERROR: InvocationError: '/bin/bash -c ! find doc/ -type f -name *.json | xargs -t -n1 python -m json.tool 2>&1 > /dev/null | grep -B1 -v ^python'
_____________________________________________________________________________________________________ summary ______________________________________________________________________________________________________
ERROR: docs: commands failed

It seem that doc/api_samples/servers/v2.19/server-put-req.json is not a valid json file.

    doc: fix malformed api sample

    I74b1a340c5ab98fdea2186e87dd13f42ce7c7661 introduced a malformed api
    sample and the tox -e docs fails since then. This patch fixes the
    sample file.
