Peter Fern b023904298 Add TCP check type 
Adds the ability to simply check whether a TCP socket accepts
connections to determine if it is healthy.  This is a light-weight -
though less comprehensive than scripting - method of checking network
service health.

The check parameter `tcp` should be set to the `address:port`
combination for the service to be tested.  Supports both IPv6 and IPv4,
in the case of a hostname that resolves to both, connections will be
attempted via both protocol versions, with the first successful
connection returning a successful check result.

Example check:

```json
{
  "check": {
    "id": "ssh",
    "name": "SSH (TCP)",
    "tcp": "example.com:22",
    "interval": "10s"
  }
}
```

Ryan Mills 275af975e8 Allow specifying a status field in the agent/service/register and agent/check/register endpoints. 
This status must be one of the valid check statuses: 'passing', 'warning', 'critical', 'unknown'.
If the status field is not present or the empty string, the default of 'critical' is used.

Nicholas Capo 98eb935392 command/agent: HTTP Check: Create httpClient in Start() 
For long (>10s) interval checks the http timeout is 10s, otherwise thetimeout is the interval. This means that a check *should* return
before the next check begins.

Nicholas Capo fb5ba8d97d command/agent: Add simple HTTP check type 
These checks make an `HTTP GET` request every Interval to the specified URL.
The status of the service depends on the HTTP Response Code.
`200` is passing, `503` is warning and anything else is failing.
