Tenant User List Action Pagination

[GeorgeMac]

The new tenant user service enforces a page limit, but does not support configuring that limit via the usual limit query parameter.

The tenant storage ListUsers enforces a default page size of 20. But as this is not parsed from the request URL parameters, 20 is always enforced:

Default enforced here:

influxdb/tenant/storage_user.go

Lines 111 to 113 in 1d75e3e

	if o.Limit > influxdb.MaxPageSize || o.Limit == 0 {
	o.Limit = influxdb.MaxPageSize
	}

Need to add limit support to:

influxdb/tenant/http_server_user.go

Lines 397 to 414 in 1d75e3e

	func decodeGetUsersRequest(ctx context.Context, r *http.Request) (*getUsersRequest, error) {
	qp := r.URL.Query()
	req := &getUsersRequest{}
	if userID := qp.Get("id"); userID != "" {
	id, err := influxdb.IDFromString(userID)
	if err != nil {
	return nil, err
	}
	req.filter.ID = id
	}
	if name := qp.Get("name"); name != "" {
	req.filter.Name = &name
	}
	return req, nil
	}
