dpp: make the protocol timeout more flexible

Browse Source 
Include a specific timeout value so different protocols can specify
different timeouts. For example once the authentication timeout
should not take very long (even 10 seconds seems excessive) but
adding PKEX may warrant longer timeouts.

For example discovering a configurator IWD may want to wait several
minutes before ending the discovery. Similarly running PKEX as a
configurator we should put a hard limit on the time, but again
minutes rather than 10 seconds.
