Since `emqx_vm:get_process_info/1` only accepts PIDs as arguments,
it's impossible for `emqx_sys_mon:procinfo/1` to return after
receiving the atom `undefined`.
This adds the information from `proc_lib:initial_call/1` and the
current stacktrace from the process info to `emqx_sys_mon:procinfo/1`
to aid in debugging some warnings with no context such as the
following:
```

* fix(flaky_test): improve live connection count test on CI
It seems that a race condition that is triggered more often in CI can
make the test fail, possibly due to the ETS write not being seen by
the subsequent read in the test.

The compile flag was introduced in EQM X 4.3 series
where CE and EE code was diverged large enough which made
non-practicle to determin edition at runtime.
such approach made testing quite challenging as we'll have to
build with different compile flags inorder to run per-edition
test cases
In this commit, we try to retrieve edition info from EMQX's
description text, (put to PT for fast access) at runtime
so we can test ALL editions from a super-set edition (EE).
* fix(dashboard_api): delete non-exist user wrongly return 204
* fix(dashboard): dashboard user should use `tags` not `tag`
* fix(dashboard): create/update user return 200 with full users list
* fix(dashboard): logout status code 204
* fix(dashboard): update pwd status code 204
* test: test suite for dashboard APIs
* refactor(dashboard): user info mnesia record name use description
* style: make elvis happy

* fix(dashboard): add/modify dashboard returns single record
* ci: update emqx-fvt version to new tag 1.0.2-dev1
* test(persistent_session_SUITE): remove redundant sleep and trap_exits
* test(persistent_session_SUITE): fix race for started snabbkaffe
Sometimes snabbkaffe was not started when publishing from a different
process. Wrap the publishing code in a ?check_trace to make sure it is
started, and make sure the publish process is truly down before ending
the trace.
* test(persistent_session_SUITE): fix takeover race
Make sure the previous session is unregistered before trying to
connect again. Sometimes the new session was trying to take over the
session that was shutting down still.
Prior to this fix, 'kick' and 'discard' calls may timeout (or
fail for other reason), failures lead to only a log, then
continue to allow the new session to get registered.
As a result, in case a client is stuck, there is no way to
force it to step down, end up with multiple connections (sessions)
for the client ID in dashboard.
After this fix, the stale pids are notified to shutdown
via a gen_server:call, and forced with a exit(Pid, kill) for any
exception happend to the gen_server:call
