Stop interpreting IPv6 addresses as regexp in hot restart (#1973)
Stop interpreting IPv6 addresses as regexp in hot restart (#1973)

Description: Stops treating ipv6 addresses as glob with certain versions of curl.

curl "http://[::1]:34871/hot_restart_version"
curl: (3) [globbing] bad range specification in column 9
curl -g "http://[::1]:34871/hot_restart_version"
curl: (7) Failed to connect to ::1 port 34871: Connection refused

Risk Level: Low: test only fix

Testing:
Ran the tests both in docker (still pass) and out (now pass) :-P
