prometheus: increase retention duration to 2y
With the move to pluto the setup is now benefitting from ZSTD compression yielding a compression factor of 2.14x, bringing our data down from 75GB to a mere 35GB. We also doubled the disk size to 512GB, so spending ~150GB on metrics is not only feasible, but will allows us to compare performance metrics over longer intervals.
