First reward is increased reward compared to other hosts hosting the content.
The previous host already hosted the content for some time, but in the end failed
and dropped out.
The new host that fills in the slot needs to store the content for shorter time
to get the final reward and hence gets higher price of slot per time ratio.
This reward though is rather non-deterministic as we can not say beforehand
when the original host will drop out.
Hence, second reward is repair-fee which is a partial amount of the original
host's collateral. The size of the reward is a fraction of slot's collateral host's collateral. The size of the reward is a fraction of slot's collateral
