List objects in file bank is not correct

[jiaopengju]

When using file bank as the backend, execute 'karbor checkpoint-list <provider-id> --plan_id <plan-id>', it will fail with “Checkpoint by-plan/1fd687b8-7c85-4936-9fe7-33ad2f923d54/79b35e99a6a541b3bcede40f590d6878/2018-11-09 could not be found. (HTTP 404) (Request-ID: req-db22a616-b3e2-4efc-9d4a-7ed70e2435ad)”

It is because that, in the bank, checkpoints by plan are stored as "<bank_path>/karbor/indices/by-plan/<plan_id>/<project_id>/<date>/<checkpoint>", the file bank plugin only list the <date> level, not include the checkpoint level.

This should be fixed.

    Fix listing checkpoints by plan error with FS bank

    When listing checkpoints by plan with using FS bank,
    it will fail with 'could not be found' error. The reason
    is, in the bank, checkpoints by plan are stored as
    "<bank_path>/karbor/indices/by-plan/<plan_id>/<project_id>
    /<date>/<checkpoint>", but the file bank plugin only list
    the <date> level, not include the checkpoint level. This
    patch will fix it.
