Remove Tink worker global timeout cli flag:

The Tink worker global timeout cli flag doesn't implement
the global timeout defined in a Tink server template correctly.

A single template can have multiple workers. So a single
Tink worker defining a global timeout for all task is
erroneous. It doesn't take the multiple workers idea into account.

A long term solution will need to be implemented. Something that
takes into account multiple workers.
