works for
aws --endpoint-url http://127.0.0.1:8333/ s3api list-objects-v2 --bucket test --prefix "fakedir"
Otherwise current calls for some methods (i.e. GetObjectAcl) ends up with wrong method selection (i.e. GetObject).
Added generic comment rule of traversing methods
ubuntu@prod-master-1:~$ aws --endpoint http://10.244.15.66:8333 s3api abort-multipart-upload --bucket prod-cache --key multipart-test --upload-id 5347f936-6adc-43de-8e5c-1fd137c3b2bc
ubuntu@prod-master-1:~$ aws --endpoint http://10.244.15.66:8333 s3api list-parts --bucket prod-cache --key multipart-test --upload-id 5347f936-6adc-43de-8e5c-1fd137c3b2bc
{
"Initiator": null,

}
If we abort a multipart upload, it appears that records are left behind. We should get a 404 NoSuchKey error.
Protocol
Otherwise any requests to the underlying handlers results in calls to
ListObjects (v1) that may intensively load gateway and volume servers.
Added the following handlers with default responses:
- GetBucketLocation
- GetBucketRequestPayment
Added the following handlers with NotFound and NotImplemented responses:
- PutBucketAcl
- GetBucketPolicy
- PutBucketPolicy
- DeleteBucketPolicy
- GetBucketCors
- PutBucketCors
- DeleteBucketCors
- one JWT for reading and one for writing, analogous to how the JWT
between Master and Volume Server works
- I did not implement IP `whiteList` parameter on the filer
Additionally, because http_util.DownloadFile now sets the JWT,
the `download` command should now work when `jwt.signing.read` is
configured. By looking at the code, I think this case did not work
before.

# Authentication with Filer
You can use mTLS for the gRPC connection between S3-API-Proxy and the filer, as
explained in [Security-Configuration](Security-Configuration) -
controlled by the `grpc.*` configuration in `security.toml`.
Starting with version XX, it is also possible to authenticate the HTTP
operations between the S3-API-Proxy and the Filer (especially
uploading new files). This is configured by setting
`filer_jwt.signing.key` and `filer_jwt.signing.read.key` in
`security.toml`.
With both configurations (gRPC and JWT), it is possible to have Filer
and S3 communicate in fully authenticated fashion; so Filer will reject
any unauthenticated communication.
```
Page `Security Overview`:
```
The following items are not covered, yet:
- master server http REST services
Starting with version XX, the Filer HTTP REST services can be secured
with a JWT, by setting `filer_jwt.signing.key` and
`filer_jwt.signing.read.key` in `security.toml`.
...
Before version XX: "weed filer -disableHttp", disable http operations, only gRPC operations are allowed. This works with "weed mount" by FUSE. It does **not work** with the [S3 Gateway](Amazon S3 API), as this does HTTP calls to the Filer.
Starting with version XX: secured by JWT, by setting `filer_jwt.signing.key` and `filer_jwt.signing.read.key` in `security.toml`. **This now works with the [S3 Gateway](Amazon S3 API).**
...
# Securing Filer HTTP with JWT
To enable JWT-based access control for the Filer,
1. generate `security.toml` file by `weed scaffold -config=security`
2. set `filer_jwt.signing.key` to a secret string - and optionally filer_jwt.signing.read.key` as well to a secret string
3. copy the same `security.toml` file to the filers and all S3 proxies.
If `filer_jwt.signing.key` is configured: When sending upload/update/delete HTTP operations to a filer server, the request header `Authorization` should be the JWT string (`Authorization: Bearer [JwtToken]`). The operation is authorized after the filer validates the JWT with `filer_jwt.signing.key`.
If `filer_jwt.signing.read.key` is configured: When sending GET or HEAD requests to a filer server, the request header `Authorization` should be the JWT string (`Authorization: Bearer [JwtToken]`). The operation is authorized after the filer validates the JWT with `filer_jwt.signing.read.key`.
The S3 API Gateway reads the above JWT keys and sends authenticated
HTTP requests to the filer.
```
Page `Security Configuration`:
```
(update scaffold file)
...
[filer_jwt.signing]
key = "blahblahblahblah"
[filer_jwt.signing.read]
key = "blahblahblahblah"
```
