feat: added cache for binary and bundle to speed up action

This commit will add a new parameter to enable cache, default to true. When cache is enabled it will cache the crc binary per arch and the bundle per preset and arch, so on next action invocations there is no need to download anddecompress which could be time consuming actions within the cluster start up
