Poor defaults in Helm chart

[jgillich]

Some of the defaults in the Helm charts seem rather poor:

• A lot of strategies are enabled by default. IMO they should be opt-in rather than opt-out; with the way values are usually merged, you'd have to manually disable 7 strategies to start from scratch
• 500m cpu request, which applies to both the cron job and the deployment. For the first one it seems unnecessary, whereas it's plain wasteful for the latter one. I'd suggest tuning it down to 100m
• The default schedule is every other minute (or every 5 minutes for deployment). Is that necessary? This could create a lot of load on the API and the nodes, wouldn't every 30-60 minutes be good enough for a default?

Thoughts?
