i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
I think this will improve the transaction response messages Kuba
mentioned where it was an empty transaction instead of a nil or not
there... if not it should make it easier to do that anyhow.
instead of defining them as being in UTC, but not including the zone
info, we will keep the standard format with zone info, but always
output the time in UTC. This means that we can parse incoming
deadlines that happen to have zone information, though I don't think
we ever need to.
also adds a "noSleep" option to the server command to avoid the 5
second sleep we introduced on startup for non-coordinator cluster
nodes. The sleep doesn't seem to be needed in the tests and makes them
much slower.
This all needs to be wired into API/Server/Cluster/Holder etc. but I
think the TransactionManager will be a pretty good building block for
managing transaction state at the coordinator level.
