Previously, we use server uuid to compose the master key name, and we
didn't store the server uuid to data file of tablespace.
So, if server uuid is changed or slave server need to use a different
uuid, the encrypted tablespace will not get the correct master key,
since the key name in key file is still composed by old server uuid.
The solution is: we need to store the uuid into page 0 of tablespace
data file. And we need to keep it to Encryption object.
