Variable precision directories and filenames

[asimihsan]

As a user, I can specify what date and time precision with which to have directories and files exposed.

For example, I may want to have directories as YYYY/MM/DD/HH/MM/SS, and files as 100's of milliseconds. This is useful for systems that output high volumes of logs and where I already what 100th millisecond to find logs at.

For example, I may want to have directories as YYYY/MM/DD and files as HH. This is useful for systems that output low volumes of logs where I'm confident that grepping over multiple hours will be fast and I'm not sure where I'm looking.
