[maint] minor dev improvements

[PGijsbers]

Change

Adds changes outline in #446:

• Change default AIOD_LOGSTASH_PORT so it does not clash with MacOS defaults
• Remove the use of sudo in the clean up script.
• Add an extra reminder to the documentation that local files are not mounted unless USE_LOCAL_DEV is set.

How to Test

• make sure you do not have AIOD_LOGSTASH_PORT set in your local override.
• start containers
• stop containers
• invoke clean script

This should all work without issues and successfully empty the data directory similar to before the PR.

@Taniya-Das this is not high priority, but I'm asking you because it would be good to test this on a non-Mac machine.

The test works well for me.
