Api create rfq response

Name `Lite`	Type	Required `Default`	Description
rfq `r`	Rfq	True	The created RFQ

A Request for Quote (RFQ) lets a taker solicit private quotes on a single instrument from makers.

Each RFQ targets one instrument (kind = STABLE_PERP) for a single requested size.
The taker may disclose a direction via rfq.side, or omit it to request a two-way (buy and sell) quote.

On submission, GRVT broadcasts the RFQ to makers over the v1.rfq feed (see RfqFeed).
Makers respond with private quotes, which the taker receives as a private quote book over the v1.quote feed (see RfqQuoteFeed).

Anonymity is automatic and always enforced — the taker and makers only ever see each other's derived anonymous account ids.
Real taker and maker identities are never exposed to the counterparty.

The RFQ lives until rfq.expiry, after which GRVT expires it and auto-cancels the makers' private quotes bound to it.
