This commit adds the functions timezone_to_offset_seconds and its alias
timezone_to_second to the rule engine. As the names suggests, these
functions convert a timzone offset string such as "+02:00", "Z", "local"
to an integer representing how many seconds that the given timezone
differs from UTC. timezone_to_offset_seconds is the one of the two
functions that should be advertised while timezone_to_second in kept for
backwards compatibility with 4.X.

This commit adds mong_date built-in functions to the rule engine
SQL-like language. Corresponding functions already existed in EMQX 4.4
and this commit makes sure that EMQX 5.X also has these functions.

Part of https://emqx.atlassian.net/browse/EMQX-9251
This ports part of the Schema Registry app from 4.x to 5.0. Here,
only support for Avro is added. Subsequent PRs will follow to add
support for other formats.
This commit adds a default timeout of 10 seconds to the rule engine's
`jq/2` function, and adds a new function `jq/3` (where the last parameter is
a timeout value). The default timeout can be configured with the setting
"rule_engine.jq_function_default_timeout".
Having a timeout when executing jq code in the rule engine is important
as jq code can potentially run forever. Also, the Erlang jq library
limits the number of jq programs that can execute concurrently so a jq
program that loops forever could potentially also prevent a "non-buggy"
jq program from ever starting.
This commit adds a function to the rule engine that alows users
to transform text or JSON objects using [jq filter programs][1].
[jq][1] is a command line tool that can be used to transform
and filter JSON text using jq's built-in language. The rule engine
function that is added with this commit uses the
[Erlang jq NIF library][2] that wraps the jq C library in an
Erlang NIF function.

The compile flag was introduced in EQM X 4.3 series
where CE and EE code was diverged large enough which made
non-practicle to determin edition at runtime.
such approach made testing quite challenging as we'll have to
build with different compile flags inorder to run per-edition
test cases
In this commit, we try to retrieve edition info from EMQX's
description text, (put to PT for fast access) at runtime
so we can test ALL editions from a super-set edition (EE).
One step closer for better code abstraction for opensorce vs enterprise
So far this relocation is to make opensource to enterprise merges
conflict free.
