Thanks to @keynslug for the insight and the patch.
With this, we avoid rewriting the parsed select clause sources, and
attempt to reuse the result context when reading values during
evaluation.
Previously, the div operation could only be used as an infix operation
while mod could only be used as a function call. After this commit, one
can use both div and mod using function call syntax and infix syntax.

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 upgrades the rulesql dependency to version 1.5 instead of
1.4. The difference between these two versions is that strings surrounded
by ' and " are supported in FROM clauses in version 1.5, but in version
1.4, only strings surrounded by " are supported.

Since buffer workers always support async calls ("outer calls"), we
should decouple those two call modes (inner and outer), and avoid
exposing the inner call configuration to user to avoid complexity.
For bridges that currently only allow sync query modes, we should
allow them to be configured with async. That means basically all
bridge types except Kafka Producer.

Currently, ingress bridges referenced in the `FROM` clause of rules
are not being accounted as dependencies.
When we try to delete an ingress bridge that's referenced in a rule
like `select * from "$bridges/mqtt:ingress"`, that bridge does not
trigger an UI warning about dependent actions.

When a bridge is disabled, its metrics are reset. With this change,
we make rule actions behave like that: disabling a rule will reset its
metrics.
