build and test with go1.14 (#195)
- https://golang.org/doc/go1.14

I did a performance sanity check in Docker, and performance seems about
the same (perhaps slightly higher).

allow any config file name if specified directly (#189)
Currently, we require that config file names end with `.yml` or `.yaml`.
This is because if the user points `-config` at a directory of files, we
only want to use the YAML files in that directory.

But this makes it more difficult to use the `-test -config` option
because config management tools might not have an extension on the file
when preparing a new config file. This change makes it so that if you
point `-config file` directly at a file, it uses it no matter what the
extension is.

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"

validate lighthouses and static hosts are in our subnet (#170)
Validate all lighthouse.hosts and static_host_map VPN IPs are in the
subnet defined in our cert. Exit with a fatal error if they are not in
our subnet, as this is an invalid configuration (we will not have the
proper routes set up to communicate with these hosts).

This error case could occur for the following invalid example:

    nebula-cert sign -name "lighthouse" -ip "10.0.1.1/24"
    nebula-cert sign -name "host" -ip "10.0.2.1/24"

    config.yaml:

        static_host_map:
            "10.0.1.1": ["lighthouse.local:4242"]
        lighthouse:
          hosts:
            - "10.0.1.1"

We will now return a fatal error for this config, since `10.0.1.1` is
not in the host cert's subnet of `10.0.2.1/24`

better windows targets in Makefile (#125)
This restores `make bin-windows` and also adds `make

GitHub Action: add release script (#124)
This script will be triggered by any tag starting with `v[0-9]+.[0-9]+.[0-9]+` (i.e.
v1.1.0). It will create all of the .tar.gz files (or .zip for windows). The amd64 binaries will be
compiled on their target systems, the rest of the Linux architecures
will be cross compiled from the Linux amd64 host.

A SHASUM256.txt will also be generated and attached to the release.

Wade Simmons bc7b3895f9 Makefile improvements
Simplify the makefile by using implicit rules. The new structure for the
build directory when using `make all` or `make release` is:

    build/$GOOS-$GOARCH-$GOARM/nebula

(The GOARM part is optional, and only used for linux-arm-6)

So, releases end up like `nebula-linux-amd64.tar.gz` or
`nebula-linux-arm-6.tar.gz`

This change also adds `-trimpath` to the build, to make the pathnames
more generic in our releases.
