Load/use feature flags with IConfiguration

[thompson-tomo]

Summary of pain point I wish for unleash to hook into IConfiguration to enable offline feature management & alternative syncing of rules. This is avoid having to implement a local api for software to call which is a no-op. Note I already have a secured solution to sync the feature flags to local servers and don't want local solution to talk directly to unleash.

The solution I'd like unleash client for dotnet includes the following:

• A dotnet configuration provider for fetching feature flags from unleash including configurable refresh interval
• unleash uses feature flag properties as defined in IConfiguration.

Describe alternatives you've considered Rolling out my own api which behaves like unleash

This is not going to get addressed in the SDK. As discussed in #183, the SDK already supports Bootstrapping and backup file loading on startup
