Allow to write audit logs on exceptions even if disabled for GET requests

[hikalkan]

• Add an option to save audit logs on exceptions on GET requests even if audit log is disabled for GET requests.
• Handle exceptions in the AuditLogMiddleware those might not be handled in the Audit action filter.

We can implement an enum named something like AuditLogLevel with;

• AuditLogLevel.All (log both gets and posts)
• AuditLogLevel.PostOnly (logs only posts)
• AuditLogLevel.ExceptionOnly (logs only exceptions of gets and posts)
• AuditLogLevel.None (no logging to db, only logs exceptions to file via ILogger)

What do you think @hikalkan? Is this seems a valid approach?

Instead add public bool AlwaysLogOnException { get; set; } = false;
