HTTPCLIENT-2028: Now allowing 0 for validateAfterInactivity

The purpose of this change is to allow stale checking all the time, in previous 
versions of HttpClient this was accomplished by 
staleConnectionCheckEnabled=true which is now removed, this adds that idea back


> Restore staleConnectionCheckEnabled=true semantic behavior in 
> validateAfterInactivity config

>             Project: HttpComponents HttpClient
>          Issue Type: Improvement
>          Components: HttpClient (classic)
>    Affects Versions: 4.5, 4.5.1, 4.5.2, 4.5.3, 4.5.4, 4.5.5, 4.5.6, 4.5.7, 
> 4.5.8, 4.5.9, 4.5.10
>            Reporter: Peter Frank

> Between HttpClient 4.4.x and 4.5.x setStaleConnectionCheckEnabled was 
> deprecated in favor of setValidateAfterInactivity.  That's all fine, however, 
> the implementation of setValidateAfterInactivity has no ability to check if a 
> connection is stale all the time.  The closest one can get is 1 ms, and 
> that's unfortunately not short enough in a test environment scenario when a 
> test Http Server is being restarted between Tests to clear out state.
> This is a common issue on the internet for people that use something like 
> Wiremock, the irony is troubleshooting the situation makes it go away (cause 
> logging slows the tests).
> I would suggest making 0 a special value to "turn on" validation all the time.
> With HttpClient 5 removing the old staleConnectionCheckEnabled completely 
> with a piece of what that feature actually did also being removed I fear it 
> will leave me, and perhaps others, in a bit of a lurch.  Thanks!
