CacheInvalidate : stop at first server not responding

[benjamin-volle]

Preconditions

All Magento versions

Steps to reproduce

1. Setup 2 Varnish servers (cache1 and cache2) in the http_cache_hosts section of "env.php"
2. Turn off the first one (cache1)
3. Try to flush the full_page by launching bin/magento cache:flush full_page

Expected result

The full_page is flushed for cache2 (the only one responding)

Actual result

The full_page is not flushed for all servers

The problem is located here :
\Magento\CacheInvalidate\Model\PurgeCache::sendPurgeRequest

In the "foreach" loop, there is a "return false" at the first exception insteag of "continue", preventing the try on all servers.
