bitbake: cooker: Clean up init/reset configuration code

Currently the cooker event data isn't rebuilt upon reset and the cache
configuration cannot be changed after init. These are both bad things
and this patch refactors the init/reset code so that it is possible
to reconfigure the server.

(Bitbake rev: 1193b8d76fcb6cb87e9ec135a2514370d7dd90ac)
