Custom Windows Event Logs integration configuration can cause Elastic Agent crashing

In Custom Windows Event Logs integration configuration there is a field to specify "Dataset name". Field is initialized with "winlog.winlog" value but it can be left empty. When you leave "Dataset name" empty and assign policy with this integration Elastic Agent starts crashing.

Windows system log repeating during faulty policy assigned to ELastic Agent:
```
The Elastic Agent service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 1000 milliseconds:

In filebeat and osquery logs these lines are repeating (about 1000 times per minute):
```
elastic-agent-client got error: rpc error: code = Unavailable desc = connection error: desc = "transport: authentication handshake failed: remote error: tls: internal error"
elastic-agent-client got error: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 127.0.0.1:6789: connectex: No connection could be made because the target machine actively refused it.
Exiting: data path already locked by another beat. Please make sure that multiple beats are not sharing the same data path (path.data).
```

After fixing integration policy on Windows system filebeat, osquery and meatricbeat processes are consuming 100% od CPU and killing those processes is nessecery.

Whole stack (Elasticsearch, Kibana, Fleet, Elastic Agent) at version 8.2.0. Except Elastic Agent running on Windows OS all other components are deployed as Docker containers.
