Feature request: ability to temporarily pause the Reloader

[nazarewk]

It would be great to pause the reloading logic for a selected workloads, for example:

1. add reloader.stakater.com/pause: "true" to Namespace to stop reloading the whole namespace
2. ~~add reloader.stakater.com/pause: "true" to workload to stop reloading the specific workload~~ this can be covered by setting the existing annotations to "false"
3. add reloader.stakater.com/pause: "true" to Secret/ConfigMap to not trigger reloads from specific configs
   • this is covered by setting reloader.stakater.com/match: "false", but only for the search-match pair scenario
   • having pause annotation overriding other annotations would make it safer for the use case below

This feature would allow editing large number of secrets at once without triggering deployments for every single change.
