seonwoo_jung 019ea06a6a Run a single hello command in MongoDB health indicators ...

The MongoDB health indicators ran the `hello` command against every
database returned by `listDatabaseNames()`. For the reactive
indicator these commands were issued in parallel via `flatMap`, so a
deployment with many databases per connection could open a connection
per database on each health check, dramatically increasing connection
usage (a regression from the Spring Data based implementation used
previously).

Since `hello` is a server-level command whose result is independent
of the target database, run it only once, against the `admin`
database if available or the first returned database otherwise. The
`databases` and `maxWireVersion` details are preserved.
