Making typed common cache so that we don't use wrong types across set/get methods and more higher-level methods can be defined for cache. Currently, we are not able to operate over all keys of the cache due to generic types. I also removed code comments around the cache. Signed-off-by: Sanket Sudake <sanketsudake@gmail.com>
