config: refactor beaker configuration

While refactoring:

 * drop support for 'cache.' prefix - it is only 'beaker.config.' that ever has
   been documented or used in examples
 * make prefix stripping more safe (if the prefix should appear twice in the key)
 * trust exactly what has been configured - drop stripping of strings
 * drop int conversion of 'expire' - beaker documentation suggests strings are fine
