Review Comment:
Wasn't the original logic, effectively:
`return idleTimeoutMillis != null && idleTimeoutMillis > 0 ?
idleTimeoutMillis : HttpClientUtil.DEFAULT_SO_TIMEOUT`
?
In general I think we should be very careful about default-setting the idle
timeout to "forever". I believe that in a majority of cases you _don't_ want
this default.

Review Comment:
Curious why setting a negative value defaults to the idle timeout but 0
means no timeout? I guess this is to preserve the existing behavior in Solr?
The underlying Jetty http request API has `<=0` signify no timeout.

Review Comment:
Should we validate that the `http2SolrClient` connectionTimeout is greater
than or equal to the `minConnTimeout`? Maybe this validation should be in the
constructor? There seems to be an expectation from the comments that this is
the "floor" for some reason... But if this is actually irrelevant then does it
make more sense to just rip out minConnTimeout altogether to avoid confusion?
