[#1] Add '-f' flag to overwrite local cache
Sometimes multiple environments have blockchains with the same magic number. In this case, user should not reuse cached chain, because cache contains magic number to identify different chains. With new '-f' flag user will be able to repopulate cache with new data for the chain with the same magic number. Signed-off-by: Alex Vanin <a.vanin@yadro.com>
