In our workflow we need to get all samples by instance_id, but
resource_id isn't useful in some meters with extra resource_id
info. For example: disk.device.read.bytes has a resource_id like
<instance_id>-<disk_type> and if we don't know disk type we
can't get samples by this resource.
In this CR regex complex query is added.
