Allow passing MemcachedClient for MemcachedHandle

[themakshter]

At the moment, the only way to pass in memcached settings for enyim is through adding these via the config settings. However, there may be circumstances where we might need to define our own MemcachedClient instance or something of the sort and set that in the CacheManager initiation. It would be nice to be able to pass in any object that implements IMemcachedClientConfiguration.

Sure, that makes sense,
Will add it to my list ^^

@themakshter Turned out I actually need the feature myself faster as expected to test the memcached handle, so, this will be in the next release ;)

[themakshter]

that's awesome! thank you very much!

Added the same option to redis, too. Now you can pass in an existing connection multiplexer.
/closing this one as it will be released soon

Hey, just to check, does this mean you cannot now just pass in the enyim section like WithMemcachedHandle("enyim.com/memcached")?

I have been testing it, and when you just try to pass the section name to the WithMemcachedHandle method, you end up with a NullReferenceException

@themakshter there is currently a bug in 0.9.3 unfortunately which causes that exception.
Actually it is a bug in the memcached client it seems, the ctor overload I'm using in that case doesn't initialize the client correctly.

The expected behavior is of course that it should also work with passing in the section name!

I reverted some changes back and it should work normal again in the next version.
Thanks for letting me know and sorry that I didn't catch it during testing ;)

No problem at all, it's good to know it got fixed!
