redo log: storage permission pre-check is need

[Tammyxia]

What did you do?

• When create changefeed with redo log storage config like this:
  [consistent]
  level = "eventual"
  max-log-size = 1
  storage = "nfs:///mnt/nfs/var/nfs"

• But some cdc server have not this directory "/mnt/nfs/var/nfs", the behavior right now is : create changefeed can be successful, but later storage persimission deny: "[CDC:ErrRedoFileOp]redo file operation: open /mnt/nfs/var/nfs/172.16.6.46:8420_mysql-test1_meta.meta.mtmp: permission denied"

• It's better if storage directory/permission is pre-checked before successfully creating changefeed.
