Added new implementation that makes the distributor accept multiple H…
…A pairs (cluster, replica) in the same requets/batch. This can be enabled with a new flag, accept_mixed_ha_samples, an will take effect only if accept_ha_samples is set to true. Fixed test by reducing the number of ingesters to 2 and replication factor to 2. Added config reference. Do not remove replica label if cluster label is not present. Added more HA mixed replicas tests with no cluster and replica labels and with cluster label only. Added e2e test for mixed HA samples in the same request. Refactored distributor mixed HA samples logic. Signed-off-by: eduardscaueru <edi_scaueru@yahoo.com>
