Jeff Mitchell 11a3ce0bdd RPC and HTTP interfaces fully generically-sockified so Unix is supported. 
Client works for RPC; will honor CONSUL_RPC_ADDR. HTTP works via consul/api;
honors CONSUL_HTTP_ADDR.

The format of a Unix socket in configuration data is:
"unix://[/path/to/socket];[username or uid];[gid];[mode]"

Obviously, the user must have appropriate permissions to create the socket
file in the given path and assign the requested uid/gid. Also note that Go does
not support gid lookups from group name, so gid must be numeric. See
https://codereview.appspot.com/101310044

When connecting from the client, the format is just the first part of the
above line:
"unix://[/path/to/socket]"

Emil Hessman cb764c35e5 add ability to specify response headers on the HTTP API 
Add an config object that allows adding HTTP header response fields to every
HTTP API response.

Each specified header is added to every response from all HTTP API endpoints.
Each individual endpoint may overwrite the specified header, which makes sure
that Consul headers such as 'X-Consul-Index' is enforced by the API.

Atin Malaviya 4732c36d88 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.

Ryan Uber b7587cac42 agent: allow config reload to modify checks/services persistence 
This change consolidates loading services and checks from both config
and persisted state into methods on the agent. As part of this, we
introduce optional persistence when calling RemoveCheck/RemoveService.

Fixes a bug where config reloads would kill persisted services/checks.
Also fixes an edge case:

1. A service or check is registered via the HTTP API
2. A new service or check definition with the same ID is added to config
3. Config is reloaded

The desired behavior (which this implements) is:

1. All services and checks deregistered in memory
2. All services and checks in config are registered first
3. All persisted checks are restored using the same logic as the agent
   start sequence, which prioritizes config over persisted, and removes
   any persistence files if new config counterparts are present.
