Add lighthouse.{remoteAllowList,localAllowList} (#217)
These settings make it possible to blacklist / whitelist IP addresses
that are used for remote connections.

`lighthouse.remoteAllowList` filters which remote IPs are allow when
fetching from the lighthouse (or, if you are the lighthouse, which IPs
you store and forward to querying hosts). By default, any remote IPs are
allowed. You can provide CIDRs here with `true` to allow and `false` to
deny. The most specific CIDR rule applies to each remote.  If all rules
are "allow", the default will be "deny", and vice-versa. If both "allow"
and "deny" rules are present, then you MUST set a rule for "0.0.0.0/0"
as the default.

    lighthouse:
      remoteAllowList:
        # Example to block IPs from this subnet from being used for remote IPs.
        "172.16.0.0/12": false

        # A more complicated example, allow public IPs but only private IPs from a specific subnet
        "0.0.0.0/0": true
        "10.0.0.0/8": false
        "10.42.42.0/24": true

`lighthouse.localAllowList` has the same logic as above, but it applies
to the local addresses we advertise to the lighthouse. Additionally, you
can specify an `interfaces` map of regular expressions to match against
interface names. The regexp must match the entire name. All interface
rules must be either true or false (and the default rule will be the
inverse). CIDR rules are matched after interface name rules.

Default is all local IP addresses.

    lighthouse:
      localAllowList:
        # Example to blacklist docker interfaces.
        interfaces:
          'docker.*': false

        # Example to only advertise IPs in this subnet to the lighthouse.
        "10.0.0.0/8": true

add configuration options for HandshakeManager (#179)
This change exposes the current constants we have defined for the handshake
manager as configuration options. This will allow us to test and tweak
with different intervals and wait rotations.

    # Handshake Manger Settings
    handshakes:
      # Total time to try a handshake = sequence of `try_interval * retries`
      # With 100ms interval and 20 retries it is 23.5 seconds
      try_interval: 100ms
      retries: 20

      # wait_rotation is the number of handshake attempts to do before starting to try non-local IP addresses
      wait_rotation: 5

add logging.timestamp_format config option (#187)
This change introduces logging.timestamp_format, which allows
configuration of the Logrus TimestampFormat setting. The primary purpose
of this change was to allow logging with millisecond precision. The
default for `text` and `json` formats remains the same for backwards
compatibility.

timestamp format is specified in Go time format, see:

 - https://golang.org/pkg/time/#pkg-constants

Default when `format: json`: "2006-01-02T15:04:05Z07:00" (RFC3339)
Default when `format: text`:
  when TTY attached: seconds since beginning of execution
  otherwise: "2006-01-02T15:04:05Z07:00" (RFC3339)

As an example, to log as RFC3339 with millisecond precision, set to:

    logging:
        timestamp_format: "2006-01-02T15:04:05.000Z07:00"
