This commit enforces the usage of AES-256
for config and IAM data en/decryption in FIPS
mode.
Further, it improves the implementation of
`fips.Enabled` by making it a compile time
constant. Now, the compiler is able to evaluate
the any `if fips.Enabled { ... }` at compile time
and eliminate unused code.

This commit changes the config/IAM encryption
process. Instead of encrypting config data
(users, policies etc.) with the root credentials
MinIO now encrypts this data with a KMS - if configured.
Therefore, this PR moves the MinIO-KMS configuration (via
env. variables) to a "top-level" configuration.
The KMS configuration cannot be stored in the config file
since it is used to decrypt the config file in the first
place.
As a consequence, this commit also removes support for
Hashicorp Vault - which has been deprecated anyway.

This commit introduces a new package `pkg/kms`.
It contains basic types and functions to interact
with various KMS implementations.
This commit also moves KMS-related code from `cmd/crypto`
to `pkg/kms`. Now, it is possible to implement a KMS-based
config data encryption in the `pkg/config` package.
