CloudCacheStore incorrectly handles JClouds' cloudServiceLocation "EU"

Infinispan's CloudCacheStore incorrectly handles the JClouds' cloudServiceLocation for Amazon S3 Ireland:

<property name="cloudServiceLocation" value="EU" />

"EU" is defined as uppercase in JClouds. This cannot be used with Infinispan because the parameter is converted to lower case in CloudCacheStore.java:183.

A possible fix that should not break existing code would be to change CloudCacheStore.java:180 from
return input.getId();
to
return input.getId().trim().toLowerCase();
