(1) The help file says that in the absence of a ipBind being specified, that it will bind to the "ip" specified. Instead, it bound to localhost which broke the default configuration. This change implements the documented behavior instead.
(2) The new IAM filer ip address has no default. This instantiates it to the same as the filer IP. I'm not sure if there should be a corresponding iam.ip or iam.ipBind option added to the filer command?
- 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"
