Add OrleansDashboard from OrleansContrib

[ReubenBond]

This PR incorporates the OrleansDashboard project from https://github.com/OrleansContrib/OrleansDashboard, created by @richorama.

As part of the PR, I renamed the package to conform to the norms for dotnet/orleans, which meant renaming the namespace to Orleans.Dashboard, with the resulting package name being Microsoft.Orleans.Dashboard.

My intention is to maintain, modernize, and further integrate and promote the dashboard as a development tool for developers working with Orleans.

For some context, this was initially discussed on Discord (join link):

• Empty conditional block should be removed. This appears to be leftover debug or development code that serves no purpose.
  src/Dashboard/Orleans.Dashboard/Metrics/History/GrainTraceEntryEqualityComparer.cs:1
• The null check is for obj.Grain but the hash calculation uses obj.Method. This should check obj.Method != null instead.
