Improve reading from and writing to Metadata pages
This change introduces a new interface IComponentMetadata.
Each LSM component is associated with a metadata object
which can be used to read and write arbitrary data to
the metadata pages of components. When flushing a
component, data in its metadata component is automatically
flushed to the disk component. For merge operations,
the IO Callback is responsible for merging the components'
metadata pages.
