HybridCache MaximumPayloadBytes not operating per documentation

[nwoolls]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

The documentation for HybridCache's MaximumPayloadBytes option indicates:

The maximum size of cache items; attempts to store values over this size will be logged and the value will not be stored in cache. 

This can be seen in the XML comments and here.

However, in practice what I am seeing is that an exception is thrown (rather than logging an error, not caching the entry, and ideally still returning the data that was to be cached).

Expected Behavior

If the payload exceeds configured limits, log an error, do not cache, and return the payload (per the docs).

Steps To Reproduce

Attempt to cache more than 1MB of data using HybridCache.

Exceptions (if any)

HybridCache lives in dotnet/extensions now. Moving the issue.

Yep, fair. Will fix ASAP.
