registry mirror repository rewrites (#3064 )

Support repository regex rewrite rules when fetching image content.

Example configuration:
```yaml
# /etc/rancher/k3s/registries.yaml
mirrors:
  "docker.io":
    endpoint:
    - "https://registry-1.docker.io/v2"
    rewrite:
      "^library/alpine$": "my-org/alpine"
```

This will instruct k3s containerd to fetch content for `alpine` images
from `docker.io/my-org/alpine` instead of the default
`docker.io/library/alpine` locations.

continuity

A transport-agnostic, filesystem metadata manifest system

This project is a staging area for experiments in providing transport agnostic metadata storage.

Please see https://github.com/opencontainers/specs/issues/11 for more details.

Manifest Format

A continuity manifest encodes filesystem metadata in Protocol Buffers. Please refer to proto/manifest.proto.

Usage

Build:

$ make

Create a manifest (of this repo itself):

$ ./bin/continuity build . > /tmp/a.pb

Dump a manifest:

$ ./bin/continuity ls /tmp/a.pb
...
-rw-rw-r--      270 B   /.gitignore
-rw-rw-r--      88 B    /.mailmap
-rw-rw-r--      187 B   /.travis.yml
-rw-rw-r--      359 B   /AUTHORS
-rw-rw-r--      11 kB   /LICENSE
-rw-rw-r--      1.5 kB  /Makefile
...
-rw-rw-r--      986 B   /testutil_test.go
drwxrwxr-x      0 B     /version
-rw-rw-r--      478 B   /version/version.go

Verify a manifest:

$ ./bin/continuity verify . /tmp/a.pb

Break the directory and restore using the manifest:

$ chmod 777 Makefile
$ ./bin/continuity verify . /tmp/a.pb
2017/06/23 08:00:34 error verifying manifest: resource "/Makefile" has incorrect mode: -rwxrwxrwx != -rw-rw-r--
$ ./bin/continuity apply . /tmp/a.pb
$ stat -c %a Makefile
664
$ ./bin/continuity verify . /tmp/a.pb

Platforms

continuity primarily targets Linux. continuity may compile for and work on other operating systems, but those platforms are not tested.
