Allow user to see which access rule is recent created or recent updated

[zhongjun]

Do as the following sequence,

1.manila access-allow user1 , the share instance access-status is active.
2.manila access-allow user2, the share instance access-status is error.
3.manila access-deny user1, the share instance access-status is active.

At last, the status of share instance access-status is active, but the wrong acess rule is still in.
If the user could see the created and updated time of share access. The user may select it and deny it.

I can't reproduce this bug with the steps indicated in the bug report:

# Add a new rule that's valid:

@Goutham Pacha Ravi (gouthamr)
This is just want to show the 'created_at' and 'updated_at' time columns when we run access_list command, it has been fix in the following patch. https://bugs.launchpad.net/manila/+bug/1682795

When we do manila access-list, the 'created_at' and 'updated_at' time
should be shown to the user. And then the user could determine which
is the recent access rule. As designed, the recent access-allow
rule caused the error access-status of share instance.
The API change [1] has been merged.
