An etcd cluster is not necessarily only dedicated to seaweedfs.
This security enhancement adds a customizable key_prefix option to the etcd filer store.
This will allow an etcd cluster administrator to limit the seaweedfs etcd user to only read/write a subset of keys under the
key_prefix, instead of all keys on the etcd cluster.
- 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"
```
Resolves: #158
tikv is causing "go mod tidy" problem. Need to resolve this before adding tikv back.
