Cypher support for date() function

[CAQ]

1. RETURN datetime("2022-10-18 00:00:00") AS a (Success)
2. RETURN datetime("2022-10-18") AS a

• failed to parse string 2022-10-18 into DateTime

3. RETURN date("2022-10-18") AS a

• unregistered function: date

Did I make a mistake on Cypher syntax, or please support the date() function. Thanks.

The date() function is not implemented yet, we will implement it later. @spasserby
