Add max-time option to curl to avoid long running ansible

When curl command is executed to check services health with `retries:
120` and `delay: 1`, it looks like it takes `120 sec` at a
maximum until it gives up. However, in case that peer does not reply
and makes timeout due to some issue, one curl takes around 1 min
(=connection timeout) to fail, so `120(sec) * 1(min) = 2 hours` in
total. It takes too long until users wait for the end of ansible.

To solve this ansible ends after long running issue, this patch adds
`--max-time 2` to curl command to timeout.
