Port of https://github.com/emqx/emqx/pull/10154 for `release-50`
Fixes https://emqx.atlassian.net/browse/EMQX-9099
Originally, the `resume_interval`, which is what defines how often a
buffer worker will attempt to retry its inflight window, was set to
the same as the `health_check_interval`. This had the problem that,
with default values, `health_check_interval = request_timeout`. This
meant that, if a buffer worker with those configs were ever blocked,
all requests would have timed out by the time it retried them.
Here we change the default `resume_interval` to a reasonable value
dependent on `health_check_interval` and `request_timeout`, and also
expose that as a hidden parameter for fine tuning if necessary.

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, Elixir expressions are evaluated on an EMQX node using the
'eval' command, which works for both Erlang and Elixir expressions.
This commit adds the new command 'eval-ex' exclusively for evaluating
Elixir expressions on Elixir nodes, similar to 'eval-erl' for Erlang.

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.
Allow installing a plugin if its name matches the beginning of another (already installed) plugin name.
For example: if plugin "emqx_plugin_template_a" is installed, it must not block installing plugin "emqx_plugin_template".

Currently, if an user configures a bridge with query mode sync, then
all calls to the underlying driver/connector ("inner calls") will
always be synchronous, regardless of its support for async calls.
Since buffer workers always support async queries ("outer calls"), we
should decouple those two call modes (inner and outer), and avoid
exposing the inner call configuration to user to avoid complexity.
There are two situations when we want to force synchronous calls to
the underlying connector even if it supports async:
1) When using `simple_sync_query`, since we are bypassing the buffer
workers;
2) When retrying the inflight window, to avoid overwhelming the
driver.
