Subject: [PATCH] Fix groupby selection

Default groupby selection for influxdb is escaped not like a regex, but as a glob. It works fine with one value in variable, but when you select multiple values, query is incorrect:
> SHOW TAG KEYS FROM "os.disk.fs.space_total" WHERE "host" =~ /{host-1,host-2}$/
