Flux 1.8.2

This holiday season release fixes a handful of annoyances, and adds an experimental --watch flag for following the progress of fluxctl release.

Fixes

• Respect proxy env entries for git operations weaveworks/flux#1556
• Only push the "sync tag" when the synced revision has changed, avoiding spurious notifications weaveworks/flux#1605
• Return any sync errors for workloads in the ListControllers API weaveworks/flux#1521

Improvements

• The experimental flag fluxctl release --watch shows the rollout progress of workloads in the release weaveworks/flux#1525
• The example manifests now include resource requests, to help Kubernetes with scheduling weaveworks/flux#1541
• We have a more comprehensive example git repo, which is
  mentioned consistently throughout the docs weaveworks/flux#1527 and weaveworks/flux#1540.
• Many clarifications and better structure in the docs weaveworks/flux{#1597, #1595, #1563, #1555, #1548, #1550, #1549, #1547, #1508, #1557}
• Registry scanning produces far less log spam, and abandons scans as soon as possible on being throttled weaveworks/flux#1538
