Fixes https://emqx.atlassian.net/browse/EMQX-10944
Also updates ekka -> 0.15.15, mria -> 0.6.4
How to test
===========
1. Start 2 or more EMQX nodes and merge them in a cluster.
2. Stop them in order.
3. Start only the first node that was stopped in the previous step.
4. Wait until the log is printed.
Or, more easily:
1. Start 2 or more EMQX nodes and merge them in a cluster.
2. Stop all but one.
3. Run `mria_mnesia:diagnosis([]).` on that node.
Example output
==============
```
Check check_open_ports should get ok but got #{msg =>
"some ports are unreachable",
results =>
#{'emqx@172.100.239.4' =>
#{open_ports =>
#{4370 => false,
5370 =>
false},
ports_to_check =>
[4370,5370],
resolved_ips =>
[{172,100,239,
4}],
status =>
bad_ports},
'emqx@172.100.239.5' =>
#{open_ports =>
#{4370 => false,
5370 =>
false},
ports_to_check =>
[4370,5370],
resolved_ips =>
[{172,100,239,
5}],
status =>
bad_ports}}}
```
After one node is back:
```
Check check_open_ports should get ok but got #{msg =>
"some ports are unreachable",
results =>
#{'emqx@172.100.239.4' =>
#{ports_to_check =>
[4370,5370],
resolved_ips =>
[{172,100,239,
4}],
status => ok},
'emqx@172.100.239.5' =>
#{open_ports =>
#{4370 => false,
5370 =>
false},
ports_to_check =>
[4370,5370],
resolved_ips =>
[{172,100,239,
5}],
status =>
bad_ports}}}
```
We need to reverse the dependency of `emqx_bridge` and `emqx_bridge_*`, because the former
loads and starts bridges during its application startup. If the individual bridge
application being loaded has not started with its dependencies, the supervision tree will
not be ready for that.

Fixes https://emqx.atlassian.net/browse/EMQX-10361
- Moves `lib-ee/emqx_ee_schema_registry` to `apps/emqx_schema_registry`.
- Removes the `_ee_` segment from module names.
- Exceptions are the table names which are kept to avoid backwards incompatibilities.
As emqx_ee_schema_registry uses Mria tables (schema_registry_shard),
a node joining a cluster needs to restart this application in order to
restart relevant Mria shard processes.

Prior to this change, when EMQX daemon mode failed to start
it's not quite easy for users to understand what went wrong.
All the know is the node did not start in time
and then instructed to boot the node in 'console' mode wishing
for some logs.
However, the node might actuay be running, causing 'console' mode
to fail with a different reason.
With this change, after a filure of daemon mode boot,
we issue a diagnosis.
1. if node can not be found from ps -ef, instruct the user
to find information in erlang.log.N
2. if the node is found running, but not responding to pings
instruct the user to check if the node name is
resolvable and reachable
3. if the node is responding to pings but emqx app is not
running, then it's likely a bug. so the user is advised
to report a github issue.
