Currently, the `directories` class is used exclusively during initialization, in the main() function. This commit refactors this class so that it is possible to use it to initialize directories much later after startup. The intent of this change is to make it possible for hints manager to create directories for hints lazily. Currently, when Scylla is booted with hinted handoff disabled, the `hints_directory` config parameter is ignored and directories for hints are neither created nor verified. Because we would like to preserve this behavior and introduce possibility to switch hinted handoff on in runtime, the hints directories will have to be created lazily the first time hinted handoff is enabled.
