ReadOnly: Dont update the record header from the calling client. While it is convenient since it avoids having to create a child process from the main dameon for writing the updated record it makes the cleitn more complex.

Remove the code in the example client code that writes the record to the local tdb.
Add code to the local ctdbd processing of replies to check if this reply contain a ro delegation and if so, spawn a child process to lock the tdb and then write the data.
