Add conditions for leave/join events for stakeholders

[jdkanani]

Following are conditions to leave/join PoS system -

• Add epoch for 100 header blocks
• Add minimum and maximum stake amount
• Add minimum lock-in period (in terms of the number of the epoch)
• Leave request
• Minimum time period (in terms of the number of the epoch) between leave request and actual leave event (+ refund stake amount)
