### StakeInstruction::DelegateStake
The Stake account is moved from Ininitialized to StakeState::Stake form. This is how stakers choose their initial delegate validator node and activate their stake account lamports. The transaction must be signed by the stake's `authorized_staker`. If the stake account is already StakeState::Stake \(i.e. already activated\), the stake is re-delegated. Stakes may be re-delegated at any time, and updated stakes are reflected immediately, but only one re-delegation is permitted per epoch.
The Stake account is moved from Initialized to StakeState::Stake form, or from a deactivated (i.e. fully cooled-down) StakeState::Stake to activated StakeState::Stake. This is how stakers choose the vote account and validator node to which their stake account lamports are delegated. The transaction must be signed by the stake's `authorized_staker`.
* `account[0]` - RW - The StakeState::Stake instance. `StakeState::Stake::credits_observed` is initialized to `VoteState::credits`, `StakeState::Stake::voter_pubkey` is initialized to `account[1]`. If this is the initial delegation of stake, `StakeState::Stake::stake` is initialized to the account's balance in lamports, `StakeState::Stake::activated` is initialized to the current Bank epoch, and `StakeState::Stake::deactivated` is initialized to std::u64::MAX
