also use a single cluster with each test creating a different index
rather than each test creating a whole new cluster.
runtime went from 38s to 30s in my informal tests
discovered that client tests weren't running due to integration build
tag. Fixed the file I needed to get through SonarCloud and documented
rest of what needs to be done in FB-1152 https://molecula.atlassian.net/browse/FB-1152
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
```
Time fields were not listed as a type which could accept key translation, causing the translation code to fail.
This also adds tests for keyed time and mutex fields.
