`discourse-common` was created in the past to share logic between the
'wizard' app and the main 'discourse' app. Since then, the wizard has
been consolidated into the main app, so the separation of
`discourse-common` is no longer useful.
This commit moves `discourse-common/(lib|utils)/*` into
`discourse/lib/*`, adds shims for the imports, and updates existing
uses in core.
* FEATURE: add penalty history when silencing a user
Display penalty history (last 6 months) when silencing/suspending a user
* FEATURE: allow default penalty values to be chosen
Adds a site setting that designates default penalty values in hours.
Silence/suspend modals will auto-fill in the default values, but otherwise
will still allow moderators to pick and overwrite values as normal.
First silence/suspend: first value
Second silence/suspend: second value
etc.
Penalty counts are forgiven at the same rate as tl3 promotion requirements do.
