Feature flags

Feature flags allows our apps (condenser mainly) to hide certain features behind flags.

Flags can be set individually for users or probabilistically to roll out a feature incrementally, for example set_flag_probability orange_theme 0.5 will enable the flag for ~50% of our users. Changing the flag probability does not re-randomize the user selection so that a user that had their flag enabled at 0.5 will still have it enabled when going to 0.75. This is achieved by seeding a PRNG with the shasum of username+flag.

Flags set individually per user always takes precedence.
