0.11 no longer uses some files from 0.10. The code was a little
too aggressive and remove these files which would break rolling back
to 0.10 if necessary. Since shards must be migrated to tsm before
upgrading to 0.11 and a user might not know they still have old shard
formats, they would not be able to revert back to 0.11 and migrate
them.
Also adds uptime stats to usage data.

Fixes#5612, #5573 and #5518.
Using the MetaExecuter, queries that need to run on both data nodes
and optionally the meta store will be executed across all data nodes
in the cluster.
This fixes a regression introduced in #5757 due to the node.ID getting
assigned by both the meta and data services. When both roles are active,
the data CreateDataNode path was not getting called because a node ID was
already assigned.
This fixes the issue by seeing if a DataNode already exists for our node
ID, and if it does not, we create one.
This fixes a couple of issues with starting meta-only nodes.
1. We were always calling CreateDataNode regardless of whether the the
node is running data services. We only call that now when node is
data enabled.
2. The node.json was created along-side creating the data node. Since
we are not creatinga a data node, this didn't happen anymore. There
wasn't a simple way to do this in one place so it's actually handle
for when creating a meta or a data node now. Since the ID assigned
to the node is the same regardless of role this works in all combinations
of roles.
3. The JoinMetaServer didn't return the ID of the joining node which
created some races when multiple nodes were joining. The join call now
returns that information to the caller.
Fixes#5754
This fixes several issues related to the bind address and hostname:
* Allows bind addresses where a hostname or IP is not specified to
work correct and bind to all interfaces by default.
* Fixes the top-level "hostname" config option to allow overridding
all bind address hostnames. This allows a node to advertise a different
hostname than what is defined in the bind address setting.
* Adds the -hostname command-line option back to allow specifing
both -join and -hostname as command-line flags.
* Enforces a configuration precedence and overriding ability defined
as config file is overridden by env vars which are overriden by command-line
flags.
Fixes#5670#5671
This removes the MetaServers property from node.json to eliminate one
of the four places those addresses are stored on disk. We always use
the values that come through the config (via file, env var or -join arg).
Under highly conncurrent write load, the coordinating node would
create a connection to any other node that is part of the replica
group. Since each connection can be expensive, OOM sitations could
occur because there was no bounds on the number of new connections
that would be created. If writes on a remote node were slow, connections
could pile up an exacerbate the problem.
This switches the pool to be bounded and has a checkout that is blocking
with a timeout. If a connection is available, it's returned immediately.
If the pool still has room for more connections, it will create one if needed.
Otherwise, the call will block until a connection becomes available or
the timeout expires. In the case of a timeout, it is propogated back up
to the PointsWriter that determine what do return to the client.
If a bind-address of :8088 is used, cluster nodes cannot
connect to those nodes because there is no hostname portion
of the address. When we see a bind-address without a hostname,
use the os hostname or localhost if that fails if it is not specified
in the config already.
* Improve the ping endpoint so that it can optionally check for leader agreement across all meta servers
* Add Ping method to the meta client
* Fix ClusterID tests
* Remove WaitForLeader from meta client and remove unnecessary references to it
* Add dir, hostname, and bind address to top level config since it applies to services other than meta
* Add enabled flags to example toml for data and meta services
* Wire up add/remove raft peers and meta servers to meta service
* Update DROP SERVER to be either DROP META SERVER or DROP DATA SERVER
* Bring over statement executor from old meta package
* Start meta service client implementation
* Update meta service test to use the client
* Wire up node ID/meta server storage information
Server registration and stats reporting has been removed from what was
once http://enterprise.influxdata.com. The app that lived there, now
runs at http://usage.influxdata.com, so that the subdomain can
eventually be repurposed. Because we also want to repurpose the
`enterprise-client` repo, we have also renamed that to `usage-client`.
InfluxDB no longer needs the `registration` service now, since all of
the endpoints it communicates with simply discard the data provided to
them.
