Thales Macedo Garitezi d6935b6a67 feat: add port scan diagnostics to mria waiting for tables checks
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
==============

```
