Timeout Bob's execution-setup after 10 seconds

Browse Source 
The execution setup is our only libp2p protocol that doesn't have
a timeout built-in. Hence, if anything fails on Alice's side, we
would wait here forever.

Wrapping the future in a timeout ensures that we fail eventually
if this protocol doesn't succeed.
