[JSWSERVER-25997] Disable all dvcs sync still sending some request to the providers according to DVCS stats

This is reproducible on Data Center: (yes)

Adding the following parameters to disable the DVCS UI sync:

dvcs.connector.synchronization.disabled
dvcs.connector.full-synchronization.disabled
dvcs.connector.pr-synchronization.disabled

Update the DVCS scheduler job time to zero to disable the hourly sync job:
- Set the JVM parameter below via setenv.sh:
```
-Ddvcs.connector.scheduler.interval=0
```
- Restart Jira.
- Run the SQL query below:
```
UPDATE clusteredjob
SET interval_millis=0 
WHERE job_runner_key='com.atlassian.jira.plugins.dvcs.scheduler.DvcsScheduler';
```
- This com.atlassian.jira.plugins.dvcs.scheduler.DvcsScheduler will trigger the sync once, and never again.
Wait for 1 -2 hours later and generate a new support zip.
Upload the support zip file into the perflog viewer and we can see some outbound requests from "Repository Request" in the DVCS stat:

DVCS shouldn't be sending any sync request to the Github, Gitlab or Bitbucket Cloud.

DVCS is sending some sync request to the Github, Gitlab or Bitbucket Cloud.

Currently there is no known workaround for this behavior. A workaround will be added here when available
