When running in GCE platform, an instance has access to:
http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/ip
Which gives back the private IP address, for example `10.240.0.2`.
http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/externalIp
Gives back the public Ip address, for example `130.211.108.21`.
As we have for `ec2`, we can support new network host settings:
* `_gce:privateIp:X_`: The private IP address of the machine for a given network interface.
* `_gce:hostname_`: The hostname of the machine.
* `_gce_`: Same as `_gce:privateIp:0_` (recommended).
Closes#13605.
Closes#13590.
BTW resolveIfPossible now throws IOException so code is also updated for ec2 discovery and
some basic tests have been added.
Closes#13854

Add paranoia
Groovy holds on to a classloader, so check it before compilation too.
I have not reviewed yet what Rhino is doing, but just be safe.

Add SpecialPermission to guard exceptions to security policy.
In some cases (e.g. buggy cloud libraries, scripting engines), we must
grant dangerous permissions to contained cases. Those AccessController blocks
are dangerous, since they truncate the stack, and can allow privilege escalation.
This PR adds a simple permission to check before each one, so that unprivileged code
like groovy scripts, can't do anything they shouldn't be allowed to do otherwise.
Plugin tests require having rest-api tests, and currently copy that spec
from a directory in the root of the plugin source into the test
resources. This change moves the rest-api-spec dir into test resources
so it is like any other test resources. It also removes unnecessary
configuration for resources from the shared plugin pom.
This commit removes unnecesssary use of ExceptionHelpers where we actually
should serialize / deserialize the actual exception. This commit also
fixes one of the oddest problems where the actual exception was never
rendered / printed if `all shards failed` due to a missing cause.
This commit unfortunately doesn't fix Snapshot/Restore which is almost
unfixable since it has to serialize XContent and read from it which can't
transport exceptions.
When running a RestIT test from the IDE, you actually start an internal node which does not automatically load the plugin you would like to test.
We need to add:
```java
@Override
protected Collection<Class<? extends Plugin>> nodePlugins() {
return pluginList(PLUGIN_HERE.class);
}
```
Everything works fine when running from maven because each test basically:
* installs elasticsearch
* installs one plugin
* starts elasticsearch with this plugin loaded
* runs the test
Note that this PR only fixes the fact we run an internal cluster with the expected plugin.
Cloud tests will still fail when run from the IDE because is such a case you actually start an internal node with many mock plugins.
And REST test suite for cloud plugins basically checks if the plugin is running by checking the output of NodesInfo API.
And we check:
```yml
- match: { nodes.$master.plugins.0.name: cloud-azure }
- match: { nodes.$master.plugins.0.jvm: true }
```
But in that case, this condition is certainly false as we started also `mock-transport-service`, `mock-index-store`, `mock-engine-factory`, `node-mocks`, `asserting-local-transport`, `mock-search-service`.
Closes#13479
Until now we had a cloud-aws plugin which is providing 2 disctinct features:
* discovery on EC2
* snapshot/restore on S3
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
