feat(cache): new fusion cache store project

[vivaticket-gpatane]

After using FusionCache for a while, I decided to create this pull request to add a new store that use the library.
https://github.com/ZiggyCreatures/FusionCache

Using FusionCache over IDistributedCache offers several advantages:

• Resilience: FusionCache handles communication issues with Redis by providing fallback mechanisms to in-memory caching, preventing application failures.
• Performance: It enhances performance by reducing latency, as data is fetched from in-memory before querying Redis.
• Advanced Features: FusionCache includes built-in features such as retries, timeouts, and cache invalidation, which are not available in IDistributedCache.
• Non-blocking Configuration: It supports non-blocking operations, minimizing the impact of cache failures on the overall application.

Stores like IDistributedCacheStore should be ignored in case of Redis errors. Currently, especially during local development, I often encounter issues where, if Redis is not running, the communication error generated by IDistributedCache causes my application to return a 500 error.

With the FusionCache store, after a Redis error, the application will continue running by moving on to the next store in the chain.

Notes

Since it is an external library to this project and is available only for Net8, I have created the following projects in which I have added the dependency on the external library.

1. Finbuckle.MultiTenant.Store.FusionCache
2. Finbuckle.MultiTenant.Store.FusionCache.Test

Let me know what you think and if it could be integrated as a feature into the project.

@dotnet-policy-service agree

Thanks! I will add this to consideration. I am toying with the idea of a side repo or branch for very specific features like this but probably will not merge into the main one since one of the goals is to stay agnostic to non .NET core libraries.

ok, it make sense, net 9 will arrive shortly and with it the new cache system, that should be very similar to fusion cache. thank again for your time and for making this amazing library.
