Use defaultCache to read default values for 107 unspecified props

[alexsnaps]

Based on issue #30, we may want to read things like capacity control (and tiering?) from the defaultCache and merge it in with the Configuration provided to javax.cache.CacheManager#createCache.

Ehcache certainly requires a capacity to be set on the Cache, which now defaults to JCacheManager. DEFAULT_SIZE. There may well be other setting we may want to "copy" from there...

Now I find that capacity set this way seems to only address an implementation issue (i.e. Ehcache requiring this setting), but I don't see how one would actually configure this one single value for all programmatically configured javax.cache.Cache to anything meaningful...

Thoughts?

I believe this calls for extending the Configuration or even CompleteConfiguration with our own to add support for the Ehcache specific configurations options.
Now the questions is: to which extent?

• Everything? if so, we may need a converter from CacheConfiguration to JSR-107 compliant one.
• Mandatory only? But then what about optional, how do you go about them? Maybe we cover the mandatory needs and defer to using Ehcache API for users having more specific needs with regards to configuration.
