ipv6_probe is a socket option supported in EMQ's otp.git fork.
If the target hostname has a ipv6 DNS resolution, gen_tcp
tries to establish a connection on ipv6.
If it fails, then a fallback to default gen_tcp:connection
* feat(http_lib): Add uri parse to emqx_http_lib
* fix(webhook): call emqx_http_lib to parse uri
* fix(auth-http): Call emqx_http_lib to parse uri
* fix(rule-engine): call emqx_http_lib to parse uri
For default tsl version and ciphers, we try to use otp release number
to determin if we want to use tlsv1.3
For default configs, we try to porivde both tlsv1.3 and
ciphers in config (even for commented out configs)
For compatibility with versions below 4.2, we still
use the `max_inflight_size` option, but generate it
as the `max_inflight`
