Reword the description of grace

[wanghao]

Now Zaqar uses "claim expiration time > current message TTL" to judge whether to extend message ttl or not. The explanation of grace "If a claimed message would normally live longer than the grace period, its expiration is not adjusted." is not very clear to users.

So we reword the description of grace to "If a claimed message would normally live longer than the claim expiration time, its expiration is not adjusted."

    Reword description of grace

    Now Zaqar uses "claim expiration time > current message TTL"
    to judge whether to extend message ttl or not.
    The explanation of grace "If a claimed message would normally
    live longer than the grace period, its expiration is not adjusted."
    is not very clear to users.

    So we reword the description of grace to "If a claimed message
    would normally live longer than the claim's live period,
    its expiration is not adjusted."
