Parameter supported in more fields like ones in INSERT

[wey-gu]

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'

I think it's caused by incorrect implementation of parameter, we'd better to bind parameter to value when parser generate AST.

Nebula team it would be really good to see this work since its been open since March of this year. I'm sure it will increase the performance of the graphd instance it will certainly make it easier to use from a client perspective.

One more point on the topic:

• Escaping strings to INSERT is very error prone, so passing strings in by parameters removes that frustration.
