Chris Earle a11f77aea0 [Monitoring] Convert "" _id to null (elastic/x-pack-elasticsearch#1098)
When Logstash 5.2 - 5.3 submit documents via the `_xpack/monitoring/_bulk`
endpoint, it sends its time-based documents with an explicit `_id` of
`""`.

This used to be automatically ignored by Monitoring, but we now accept the
_id that we are given (including `null`). ES, prior to 5.3.1, accepted
`""` as a valid `_id` through the `_bulk` endpoint, which means that it
blindly accepted and overwrote documents given that ID, meaning that all
Logstash instances "shared" the exact same document and therefore the UI
becomes useless.

This change allows `""` to be used and it simply replaces that value, and
only that value, with `null`. This enables backwards compatibility with LS
5.2 - 5.3.0.

= Elasticsearch X-Pack

A set of Elastic's commercial plugins for Elasticsearch:

- License
- Security
- Watcher
- Monitoring
- Machine Learning
- Graph

= Setup

You must checkout `x-pack-elasticsearch` and `elasticsearch` with a specific directory structure. The
`elasticsearch` checkout will be used when building `x-pack-elasticsearch`. The structure is:

- /path/to/elastic/elasticsearch
- /path/to/elastic/elasticsearch-extra/x-pack-elasticsearch

== Vault Secret

The build requires a Vault Secret ID. You can use a GitHub token by following these steps:

1. Go to https://github.com/settings/tokens
2. Click *Generate new token*
3. Set permissions to `read:org`
4. Copy the token into `~/.elastic/github.token`
5. Set the token's file permissions to `600`

```
$ mkdir ~/.elastic
$ vi ~/.elastic/github.token
# Add your_token exactly as it is into the file and save it
$ chmod 600 ~/.elastic/github.token
```

If you do not create the token, then you will see something along the lines of this as the failure when trying to build X-Pack:

```
* What went wrong:
Missing ~/.elastic/github.token file or VAULT_SECRET_ID environment variable, needed to authenticate with vault for secrets
```

=== Offline Mode

When running the build in offline mode (`--offline`), it will not required to have the vault secret setup.

== Native Code

**This is mandatory as tests depend on it**

Machine Learning requires platform specific binaries, build from https://github.com/elastic/machine-learning-cpp via CI servers.

The native artifacts are stored in S3. To retrieve them infra's team Vault service is utilized, which 
requires a github token. Please setup a github token as documented: 

https://github.com/elastic/infra/blob/master/docs/vault.md#github-auth

The github token has to be put into ~/.elastic/github.token, while the file rights must be set to 0600.
