CockroachDB collects query metrics and separates them by application name and we were not setting the correct application name for the cockroachkv client. This PR calls our existing function that appends it to the connection string.

the relatively small batch size of 128 was chosen so that if we have
a set of keys like
a/1
a/2
...
a/100000
b
c
list operations would not have to walk 100k keys inside of a/ before
skipping to b. unfortunately, iteration is also used by the metainfo
loop. in that case, it's doing a recursive listing, and so there's
no need to skip large prefixes. thus, we can use a bigger batch
size when recursive listing is requested.

this will allow us to inspect the type of `db.Driver()` on *sql.DB
connections to correctly differentiate between pg and crdb conns.
as a bonus, this moves all concerns about when to replace "cockroach://"
with "postgres://" out of view, letting the thin shim "driver" take care
of that.
