IGNITE-2786 : SpringCache doesn't survive client reconnect

[ryagnik]

The fix can be applied as follows with SpringCacheManager -

1. Design was to listen for ignite re connect event
2. And clear the cache on reconnect
3. Added logger to log reconnect information

See the following code below and let us know if this is helpful -

In afterPropertiesSet -

//Handles the reconnect event, on server crashes OR network failure, client
connects to server and
// destroy the cache
IgnitePredicate lsnr = iEvt -> {
U.warn(log,"Received discovery event [iEvt=" + iEvt.name() + ", discovery=" + iEvt.shortDisplay() + ']');

caches.keySet().forEach(key ->
{ ignite.destroyCache(key); caches.remove(key); }

);
