feature_multikeysporks.py

Test logic for several signer keys usage for spork broadcast.

We set 5 possible keys for sporks signing and set minimum
required signers to 3. We check 1 and 2 signers can't set the spork
value, any 3 signers can change spork value and other 3 signers
can change it again.
