As plugin/proxy always returns compressed messages, it's important to
set this before calling Scrub(), as some messages will be unnecessarily
truncated otherwise.
With Go 1.9 you *can* include the std lib's context package and nothing
breaks. However we never officially made the move (and grpc also doesn't
ues the std lib's one).
Standardize all plugins on using the extern context package.
Fixes#1466
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
