Description

A user from slack (and also from my side) would consider it's nice to support so ;).

(root@nebula) [basketballplayer]> :param t => "player1000"

(root@nebula) [basketballplayer]> insert vertex player(name,age) values $t:("foo bar", 20);
[ERROR (-1004)]: SyntaxError: Parameter is not supported in vid near `$t'

Contributor guide

Research direction
Investigate the parser and execution engine to understand where parameters are resolved for INSERT statements. Look at the syntax for `:param` and how it's handled in other statements like `MATCH` or `GO`, then extend that to the vid field in `INSERT VERTEX`.
