When using S3 or EC2, it was possible to use a proxy to access EC2 or S3 API but username and password were not possible to be set.
This commit adds support for this. Also, to make all that consistent, proxy settings for both plugins have been renamed:
* from `cloud.aws.proxy_host` to `cloud.aws.proxy.host`
* from `cloud.aws.ec2.proxy_host` to `cloud.aws.ec2.proxy.host`
* from `cloud.aws.s3.proxy_host` to `cloud.aws.s3.proxy.host`
* from `cloud.aws.proxy_port` to `cloud.aws.proxy.port`
* from `cloud.aws.ec2.proxy_port` to `cloud.aws.ec2.proxy.port`
* from `cloud.aws.s3.proxy_port` to `cloud.aws.s3.proxy.port`
New settings are `proxy.username` and `proxy.password`.
```yml
cloud:
aws:
protocol: https
proxy:
host: proxy1.company.com
port: 8083
username: myself
password: theBestPasswordEver!
```
You can also set different proxies for `ec2` and `s3`:
```yml
cloud:
aws:
s3:
proxy:
host: proxy1.company.com
port: 8083
username: myself1
password: theBestPasswordEver1!
ec2:
proxy:
host: proxy2.company.com
port: 8083
username: myself2
password: theBestPasswordEver2!
```
Note that `password` is filtered with `SettingsFilter`.
We also fix a potential issue in S3 repository. We were supposed to accept key/secret either set under `cloud.aws` or `cloud.aws.s3` but the actual code never implemented that.
It was:
```java
account = settings.get("cloud.aws.access_key");
key = settings.get("cloud.aws.secret_key");
```
We replaced that by:
```java
String account = settings.get(CLOUD_S3.KEY, settings.get(CLOUD_AWS.KEY));
String key = settings.get(CLOUD_S3.SECRET, settings.get(CLOUD_AWS.SECRET));
```
Also, we extract all settings for S3 in `AwsS3Service` as it's already the case for `AwsEc2Service` class.
Closes#15268.
With 2.0, we now bind to `localhost` by default instead of binding to the network card and use its IP address.
When the discovery plugin gets from AWS API the list of nodes that should form the cluster, this list is pinged then. But as each node is bound to `localhost`, ping does not get an answer and the node elects itself as the master node.
`network.host` must be set.
Closes#13589.
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.
