> Provide a means of configuring a maximum lifetime for HttpClient connections.  Currently,
it would appear as long as a connection is used it may persist indefinitely.
> This would be useful for situations where HttpClient needs to react to DNS changes, such
as the following situation that may occur when using DNS load balancing:
>  - HttpClient maintains connections to example.com which resolves to IP A
>  - Machine at IP A fails, and example.com now resolves to backup machine at IP B
>  - Since IP A is failing, connections are destroyed, and new connections are made to
IP B
>  - Machine at IP A recovers, but HttpClient maintains connections to IP B since the connections
are still healthy
> The desired behavior would be that connections to IP B will reach their connection lifetime,
and new connections could be created back to IP A according to the updated DNS settings.
