Hi guys!
Now IoTDB supports the following path patterns:
* (1 asterisk) - one layer
** (2 asterisks) - one or more layers
We need to support a new path pattern: 0 or one or more layers, there are
some optional schemes:
Scheme 1, support it directly with a specific syntax:
*** (3 asterisks) - 0 or one or more layers
Scheme 2, use more common syntax:
a special symbol (such as $, or someone else) - 0 or 1 layer
$* - 0 or 1 or more layers

Any ideas?
