Log Message:
Updated sysutils/fabric to 1.12.0.
Changelog from 1.11.1 :
- Fix a relative import in fabric.network to be
  correctly/consistently absolute instead.
- Implement sudo-specific password caching.
  This can be used to work around issues where over-eager submission of
  env.password at login time causes authentication problems
  (e.g. during two-factor auth).
