There are two types of AWS security credentials:
* long-term credentials (access key id + secret access key)
* temporary credentials (access key id + secret access key + session token)
The KMS host can obtain these credentials from multiple sources:
* IMDS (config option `aws_use_ec2_credentials`)
* STS, by assuming an IAM role (config option `aws_assume_role_arn`)
* Scylla config (options `aws_access_key_id`, `aws_secret_access_key`)
* Env vars (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`)
* AWS credentials file (~/.aws/credentials)
First two sources return temporary credentials. The rest return
long-term credentials.
Extend the KMS host to support temporary credentials from the other
three sources as well. Introduce the config option `aws_session_token`,
and parse the same-named env var and config option from the credentials
file. Also, support `aws_security_token` as an alias, for backwards
compatibility.
This patch facilitates local debugging of corrupted SSTables, as well as
testing, using temporary credentials obtained from STS through other
authentication means (e.g., Okta + gimme-aws-creds).

The help string for the `--kms-hosts` command-line option mentions only
the AWS credentials file as a fall-back search path, in case no explicit
credentials are given.
Extend the help string to mention the environment as well. Make it clear
that the environment has higher precedence than the credentials file.

This commit eliminates unused boost header includes from the tree.
Removing these unnecessary includes reduces dependencies on the
external Boost.Adapters library, leading to faster compile times
and a slightly cleaner codebase.

Bulk transfer of EAR functionality. Includes all providers etc.
Could maybe break up into smaller blocks, but once it gets down to
the core of it, would require messing with code instead of just moving.
So this is it.
Note: KMIP support is disabled unless you happen to have the kmipc
SDK in your scylla dir.
Adds optional encryption of sstables and commitlog, using block
level file encryption. Provides key sourcing from various sources,
such as local files or popular KMS systems.
