• Stake funds with a pool. The amount to bond is transferred from the member to the pools account and immediately increases the pools bond.

    Note:

    • An account can only be a member of a single pool.
    • An account cannot join the same pool multiple times.
    • This call will not dust the member account, so the member must have at least existential deposit + amount in their account.
    • Only a pool with [PoolState::Open] can be joined
