Chase casting types.CheckID to a string into the state_store.
It turns out the indexer can only use strings as arguments when
creating a query.  Cast `types.CheckID` to a `string` before calling
into `memdb`.

Ideally the indexer would be smart enough to do this at compile-time,
but I need to look into how to do this without reflection and the
runtime package.  For the time being statically cast `types.CheckID`
to a `string` at the call sites.

Sean Chittenden f3a69c939d Refactor consul.serverParts into server_details.ServerDetails
This may be short-lived, but it also seems like this is going to lead us down a path where ServerDetails is going to evolve into a more powerful package that will encapsulate more behavior behind a coherent API.

Atin Malaviya b623af776b Consul Session TTLs
The design of the session TTLs is based on the Google Chubby approach
(http://research.google.com/archive/chubby-osdi06.pdf). The Session
struct has an additional TTL field now. This attaches an implicit
heartbeat based failure detector. Tracking of heartbeats is done by
the current leader and not persisted via the Raft log. The implication
of this is during a leader failover, we do not retain the last
heartbeat times.

Similar to Chubby, the TTL represents a lower-bound. Consul promises
not to terminate a session before the TTL has expired, but is allowed
to extend the expiration past it. This enables us to reset the TTL on
a leader failover. The TTL is also extended when the client does a
heartbeat. Like Chubby, this means a TTL is extended on creation,
heartbeat or failover.

Additionally, because we must account for time requests are in transit
and the relative rates of clocks on the clients and servers, Consul
will take the conservative approach of internally multiplying the TTL
by 2x. This helps to compensate for network latency and clock skew
without violating the contract.

Robert Xu a2fea2ce55 Utilise new raft.SetPeers() method, move expect logic to leader.go.
This way, we don't use EnableSingleMode, nor cause chaos adding peers.

Robert Xu 31c392813c Add expect bootstrap '-expect=n' mode.
This allows for us to automatically bootstrap a cluster of nodes after
'n' number of server nodes join. All servers must have the same 'n' set, or
they will fail to join the cluster; all servers will not join the peer set
until they hit 'n' server nodes.

If the raft commit index is not empty, '-expect=n' does nothing because it
thinks you've already bootstrapped.
