[FEATURE] 📜 Custom Plugins Log Levels

[jodydonetti]

Is your feature request related to a problem? Please describe

Currently FusionCache allows customization of a lot of different log levels to be used in different scenarios, such as for serialization errors, factory errors, factory synthetic timeouts, backplane errors, etc.

When talking about plugins though, this is not the case: every log message is either Information (for things like "a plugin has been added") or Error (for things like when an error occurred while adding a plugin, etc).

Describe the solution you'd like

Based on a request by community member @shoaibshakeel381 , FusionCache may add a couple of custom log levels, related to plugins.

In particular, 2 new options will be added in the FusionCacheOptions class:

public LogLevel PluginsInfoLogLevel { get; set; }
public LogLevel PluginsErrorsLogLevel { get; set; }

Their default values will be, respectively, LogLevel.Information and LogLevel.Error.
