SERVER-4217 updated detailed log format to include log severity and component name.

    Log severity is logged with a single capital letter.
        F - Severe
        E - Error
        W - Warning
        I - Info and Debug Level 0
        D - All debug levels > 0
    Component name is logged in upper-case padded with trailing spaces to fit within 8 characters.
