Renaming LogLevel.Verbose to Trace #299

[JunTaoLuo]

Issue #299
Renaming LogLevels in logging so that Verbose is renamed to Trace and is considered less severe than Debug.

Most severe level listed first:

Current Levels	New Levels
Critical	Critical
Error	Error
Warning	Warning
Information	Information
Verbose	Debug
Debug	Trace

I will update the affected repos:

• DataProtection Reacting to verbose rename DataProtection#112
• UserSecrets Reacting to verbose rename UserSecrets#52
• dnx-watch Reacting to verbose rename DotNetTools#39
• Hosting Reacting to verbose rename Hosting#512
• WebListener Reacting to verbose rename HttpSysServer#157
• EntityFramework Reacting to verbose rename dotnet/efcore#3998
• StaticFiles Reacting to verbose rename StaticFiles#95
• Routing Reacting to verbose rename Routing#246
• Diagnostics Reacting to verbose rename Diagnostics#224
• Session Reacting to verbose rename Session#77
• Security Reacting to verbose rename Security#608
• MVC Reacting to verbose rename Mvc#3701
• Identity Reacting to verbose rename Identity#667
• SignalR-Server https://github.com/aspnet/SignalR-Server/pull/142
• SignalR-Redis Reacting to verbose rename SignalR-Redis#22
• SignalR-SqlServer Reacting to verbose rename SignalR-SqlServer#17
• SignalR-ServiceBus Reacting to verbose rename SignalR-ServiceBus#11
• Performance https://github.com/aspnet/Performance/pull/12
• KestrelHttpServer Reacting to verbose rename KestrelHttpServer#459
• IISIntegration Reacting to verbose rename IISIntegration#47

To keep the current order of severity existing Verbose messages will be changed to Debug and existing Debug messages will be changed to Trace.

I am a bit confused...the title says Verbose is becoming Trace, but the above statement is different...which is correct?

@kichalla the original intent of #299 was to swap the order of verbose and debug. But it was later decided to rename verbose to trace. To illustrate how the current severity level are maintained, take a look at DataProtection
