[Bug] QueryResult parsing fails on node labels retrieval on read only replicas

[marcinc]

I noticed an issue with the QueryResult -> parseRecords logic when running a query against a redis read-only replica. Specific issue around Labels retrieval that it called internally when parsing a node:

redisgraph-go/query_result.go

Line 143 in 3b0ad09

values[idx] = qr.parseNode(c)

redisgraph-go/query_result.go

Line 178 in 3b0ad09

labels[i] = qr.graph.getLabel(labelIds[i])

Turned out the Labels() calls procedure internally

redisgraph-go/graph.go

Lines 283 to 284 in 3b0ad09

	func (g *Graph) Labels() []string {
	qr, _ := g.CallProcedure("db.labels", nil)

which disregards the mode for that procedure and always attempts to run RW g.Query(q) which will obviously fail on read-only replicas.

redisgraph-go/graph.go

Line 279 in 3b0ad09

return g.Query(q)

I'm happy to submit a PR for this issue as I've already solved it in my current project.
