Since Go 1.7, context is a standard package, superceding the
"x/net/context". Since Go 1.9, the latter only provides a few type
aliases from the former. Therefore, it makes sense to switch to the
standard package.
This commit was generated by the following script (with a couple of
minor fixups to remove extra changes done by goimports):
#!/bin/bash
if [ $# -ge 1 ]; then
FILES=$*
else
FILES=$(git ls-files \*.go | grep -vF ".pb.go" | grep -v
^vendor/)
fi
for f in $FILES; do
printf .

goimports -w $f
awk ' /^$/ {e=1; next;}
/[[:space:]]"context"$/ {e=0;}
{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
mv $f.new $f
