Updated durable functions templates in C# to use nameof

[lbugnion]

This uses nameof wherever possible instead of magic strings. This makes navigating to the symbols (F12 in Visual Studio) much easier and more convenient. It also avoids errors when renaming a method.

Thanks @lbugnion.

Thanks for your contribution. This seems right to me but, before merging, I think it'd be good to check-in with @AnatoliB and @cgillum as to whether or not we want to incorporate this pattern into the templates. If possible, I'd like to wait until they can give this an approval themselves :)

@davidmrdavid @AnatoliB @cgillum - any thoughts on this before we merge?

[davidmrdavid]

My advice still stands: I like the change, but I want to get at least one more DF person to approve since this affects our quickstart experience. I'll wait for either of the tagged folks above to chime in :-)

@liliankasem go ahead and merge then!
