Maintain available shards set.
...
This commit removes the previous `MaxShard` tracking and replaces
it with an `Available Shards` set tracking. This allows sparse shard
tracking without implicitly tracking all shards in between.

make sure cluster gets into DEGRADED state when adding nodes
...
previously, losing a node could cause the cluster to go from NORMAL->DEGRADED,
but adding a node would not cause it to go from STARTING->DEGRADED. Cody brought
this up in code review.

support DEGRADED in removeNode
...
now, nodes which have failed and been removed from the running cluster state can
still be manually removed to trigger a cluster resize event. This is important
because otherwise there is no way to cause the cluster to resize itself if a
node fails and you don't want to add a node to replace it.

add degraded cluster state and handle node failure
...
cluster is in degraded state when some number of nodes greater than 0 but less
than replicaN have failed. This is sort of a hybrid of "STARTING" and "NORMAL"
states because we can still respond to queries as in the NORMAL state, but we
need to be alert to re-add nodes to the cluster if they come back online which
required some changes to the cluster logic.
In order to make debugging easier, the test.MustRunCluster functionality now
names the nodes in the cluster explicitly as "node0", "node1", etc. "node0" is
the coordinator.
A number of TODOs are left in the test for scenarios that need to be checked.
