Vendor the external cookbooks

Knife-Zero doesn't include Berkshelf support, so vendoring everything in
the repo is convenient again

+# IPFS Cookbook
+
+This cookbook installs go-ipfs and starts it as a daemon
+
+## Requirements
+
+### Platforms
+
+This cookbook is tested on Ubuntu 18.06, 16.04 and Debian 9 using Test Kitchen.
+It currently only supports 64bit platforms
+
+### Chef
+
+- Chef 12.5 or later (the cookbook provides a
+  [Custom Resource](https://docs.chef.io/custom_resources.html) to configure
+  go-ipfs)
+
+### Cookbook dependencies
+
+- `ark` to download and uncompress the go-ipfs package
+
+## Usage
+
+### ipfs::default
+
+Just include `ipfs` in your node's `run_list`:
+
+```json
+{
+  "name":"my_node",
+  "run_list": [
+    "recipe[ipfs]"
+  ]
+}
+```
+
+## Attributes
+
+- `node['ipfs']['version']` - the go-ipfs version to download from the official
+site (64bit)
+- `node['ipfs']['checksum']` - the SHA256 checksum for the package
+- `node['ipfs']['config']` - a hash of config options
+
+## Resources
+
+`ipfs_config` sets the config. Supports hashes, arrays, booleans and strings.
+Does not change anything if the config already has that value, and restarts
+the server automatically
+
+```ruby
+ipfs_config "Gateway.Writable" do
+  value "true"
+ end
+```
+
+## Running the specs and integrations tests
+
+Install the latest [Chef DK](https://downloads.chef.io/chefdk).
+
+```
+chef exec delivery local all # Run the linting check, syntax check and unit tests
+kitchen verify # Run the integration tests for Ubuntu 16.04, 18.06 and Debian 9
