UP means the metadata proxy is working fine on both transport-nodes(if configured);
DOWN means the metadata proxy is is down on both transport-nodes(if configured),
hence the metadata proxy will not repsond to any metadata request;
Error means there is an error on transport-node(s) or no status is reported from
transport-node(s). The metadata proxy may be working (or not working);
NO_BACK means metadata proxy is working on one of the transport node while
not in the other transport-node (if configured). If the metadata proxy on
the working transport-node goes down, the metadata proxy will go down.
Required Enum: UP, DOWN, ERROR, NO_BACKUP
ids of transport nodes where this metadata proxy is running
Order of the transport nodes is insensitive because Metadata Proxy
is running in Active-Active mode among target transport nodes.
