feat: Deprecate embedded browser and import console (#12460 )

This feature also changes the default port where
the browser is running, now the port has moved
to 9001 and it can be configured with

```
--console-address ":9001"
```

AssumeRole

Introduction

Returns a set of temporary security credentials that you can use to access MinIO resources. AssumeRole requires authorization credentials for an existing user on MinIO. The advantages of this API are

To be able to reliably use S3 multipart APIs feature of the SDKs without re-inventing the wheel of pre-signing the each URL in multipart API. This is very tedious to implement with all the scenarios of fault tolerance that's already implemented by the client SDK. The general client SDKs don't support multipart with presigned URLs.
To be able to easily get the temporary credentials to upload to a prefix. Make it possible for a client to upload a whole folder using the session. The server side applications need not create a presigned URL and serve to the client for each file. Since, the client would have the session it can do it by itself.

The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations. The policy applied to these temporary credentials is inherited from the MinIO user credentials. By default, the temporary security credentials created by AssumeRole last for one hour. However, use the optional DurationSeconds parameter to specify the duration of the credentials. This value varies from 900 seconds (15 minutes) up to the maximum session duration of 7 days.

API Request Parameters

Version

Indicates STS API version information, the only supported value is '2011-06-15'. This value is borrowed from AWS STS API documentation for compatibility reasons.

Params	Value
Type	String
Required	Yes

AUTHPARAMS

Indicates STS API Authorization information. If you are familiar with AWS Signature V4 Authorization header, this STS API supports signature V4 authorization as mentioned here

DurationSeconds

The duration, in seconds. The value can range from 900 seconds (15 minutes) up to 7 days. If value is higher than this setting, then operation fails. By default, the value is set to 3600 seconds.

Params	Value
Type	Integer
Valid Range	Minimum value of 900. Maximum value of 604800.
Required	No

Policy

An IAM policy in JSON format that you want to use as an inline session policy. This parameter is optional. Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the canned policy name and the policy set here. You cannot use this policy to grant more permissions than those allowed by the canned policy name being assumed.

Params	Value
Type	String
Valid Range	Minimum length of 1. Maximum length of 2048.
Required	No

Using AssumeRole API

$ export MINIO_ROOT_USER=minio
$ export MINIO_ROOT_PASSWORD=minio123
$ minio server ~/test

Create new users following the multi-user guide here

Testing with an example

Use the same username and password created in the previous steps.

[foobar]
region = us-east-1
aws_access_key_id = foobar
aws_secret_access_key = foo12345

NOTE: In the following commands --role-arn and --role-session-name are not meaningful for MinIO and can be set to any value satisfying the command line requirements.

$ aws --profile foobar --endpoint-url http://localhost:9000 sts assume-role --policy '{"Version":"2012-10-17","Statement":[{"Sid":"Stmt1","Effect":"Allow","Action":"s3:*","Resource":"arn:aws:s3:::*"}]}' --role-arn arn:xxx:xxx:xxx:xxxx --role-session-name anything
