satellite/metabase: custom error for commit object

Browse Source 
We stoped returning lots of errors as is to avoid leaking our internals
but some errors were meanigful for client. Example of such error is
"exceeded maximum number of parts". With this change we are wrapping
some important commit object errors with new ErrFailedPrecondition
error to be able to return it easily to uplink.
