Bug Report

What happened:
We have ~6k SLOs in one environment and with them re-syncing every hour due to the defaultForceSyncPeriod here we are hitting our API limit for slo_get. It has been raised but we do not need to be re-syncing SLOs every hour, most of our other operators re-reconcile on a 4-8 hour cadence. I understand the concern of not wanting the UI to drift from what is in the cluster for an extended period of time, either from manual changes or other edits, but I'd like to have the option to either shorten or extend it depending on the use case. For SLOs I'd like to spread it out but I could see other cases where one may want to keep it in sync more often.

What I expected:
I would like to be able to configure the forceSyncPeriod to override the defaultForceSyncPeriod to change when resources are re-synced to Datadog.

There is likely some conversation around if this should be configurable per type (monitor, dashboard, SLO, ect.) or a global definition to replace the default 60 minutes for all of them.

Steps to Reproduce

1. Install the operator as usual
2. Apply any resource to the cluster
3. Wait 1 hour and the resource will be re-applied and the .status.lastForceSyncTime is updated
4. Repeat
