fix(config): add missing enum constructors for `shared_subscription_strategy`
Currently, there's [code](048afa6d2d/apps/emqx/src/emqx_shared_sub.erl (L270-L279)) and tests that expect the possibility of
values `sticky`, `hash_topic` and `hash_clientid` in the
`node.shared_subscritpion_strategy` configuration, but the schema enum
does not contain those constructors.
There's also a `hash` constructor expected, but apparently it's just for backwards compatibility (same as `hash_clientid`), so maybe we can skip it in 5.0

Keeping headers in the src directory makes sense for the interfaces we
don't want to expose outside, but the `include_lib` directive fails to
compile under Mix. Changing `include_lib("emqx_gateway/src/...")` to
`-include("src/...")` pleases both Mix and Rebar.
While declaring `emqx_conf` as an application dependency of
`emqx_resource` worked for releases, it messed up the startup
relationship during tests. Since only removing `emqx_conf` from the
`applications` key in `emqx_resource` breaks the list of apps that
need to be rebooted on config changes (since `emqx_conf` is not on any
apps dependencies list, it was not being added to the final
topologically sorted list), we now always add it as a vertex to ensure
its presence there. This (apparently) makes the rebar3 release, the
mix release and test runs behave normally.
As described in the 5.0 specification, we should disconnect clients that
exceed the receive-maximum limit.

fix: #6447
Adding hocon to emqx solves the issue, since other offending apps
depend on emqx. The warnings were that it was not able to find info
on the `hocon_schema` behaviour.
Example:
```
Callback info about the hocon_schema behaviour is not available
```
By treating the apps in the umbrella as dependencies to be managed and
built by rebar3, we can simplify the maintenance of the release, at
the cost of increased build times: using Mix as before, it could track
changed files better than using rebar. But the complexity and
possibility of discrepancies make it using rebar much more compelling.
This commit enables a minimal working build of EMQX release using
Mix. However, to properly start the release, several configuration
steps are still missing. A `mix_release.sh` script does a few hacks
to get the release built with Mix to start properly, by first assuming
that `make emqx` has been run prior to the release, ran once to
generate the `app.*.config` files, and then it copies that and some
other files to the expected places.
Also, `emqx_telemetry` hangs the start procedure because it thinks
it's in an official release and tries to make a request. We disable
it temporarily via config just to get a working build for now.
