PEL: Add repository to save PELs

Create the Repository class that can save PELs in (and later retrieve
them from) the filesystem.  It provides an add() method that can add
a PEL object to the repository.

Now, when the Manager class sees an OpenBMC event log created with the
RAWPEL metadata in the AdditionalData property that points at a file
that contains a PEL, it can save that PEL.  Before the PEL is saved, the
log ID and commit timestamp fields in the PEL will be updated - the log
ID to a unique value, and the timestamp to the current time.
