Receivers currently panic when retrieving labels for a TSDB that is being initialized. The reason for this is that the tenant is added to the tenants map and the TSDB is started in the background. When retrieving labels, the MultiTSDB creates Clients for each TSDB, even if a TSDB is not yet ready. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>
