JustPlanningPoker to start gathering server-side diagnostics

[PolygeneLubricants]

Hi all,

It has always been one of the core philosophies of this project, to not gather any user metrics which potentially can be shared with third-party vendors. I initially extended this to any server-side metrics as well, to ensure there were no grey areas or flexible principles.
By not logging any server-side information, I don't have any insight in unhandled exceptions, downtime or unreported errors, which significantly limits my ability to catch and fix any bugs which may arise.

With your permission, I would like to start logging server-side technical diagnostics (not any user data), to ensure the product can remain as bug-free as possible.

If you find any parts of this that you disagree with, or where I may have misunderstood the extend of data being collected, please join the discussion, and I/we can adjust the code accordingly, to adhere to the core principle, of not logging any user data.
