Add projectName configuration option
Add projectName configuration option

When your application's package.json uses a scoped name (e.g.,
@myorg/project) then that name cannot be used in the rowKey for the
Azure Table entity.

You should supply the new projectName configuration value in your
config/deploy.js to a valid name (do not use /, \, # nor, ?).
