* auth/aws: Make identity alias configurable
This is inspired by #4178, though not quite exactly what is requested
there. Rather than just use RoleSessionName as the Identity alias, the
full ARN is uses as the Alias. This mitigates against concerns that an
AWS role with an insufficiently secured trust policy could allow an
attacker to generate arbitrary RoleSessionNames in AssumeRole calls to
impersonate anybody in the Identity store that had an alias set up.
By using the full ARN, the owner of the identity store has to explicitly
trust specific AWS roles in specific AWS accounts to generate an
appropriate RoleSessionName to map back to an identity.
Fixes#4178
* Respond to PR feedback
* Remove CreateOperation
Response to PR feedback
* Add AWS Secret Engine Root Credential Rotation
This allows the AWS Secret Engine to rotate its credentials used to
access AWS. This will only work when the AWS Secret Engine has been
provided explicit IAM credentials via the config/root endpoint, and
further, when the IAM credentials provided are the only access key on
the IAM user associated wtih the access key (because AWS allows a
maximum of 2 access keys per user).
Fixes#4385
* Add test for AWS root credential rotation
Also fix a typo in the root credential rotation code
* Add docs for AWS root rotation
* Add locks around reading and writing config/root
And wire the backend up in a bunch of places so the config can get the
lock
* Respond to PR feedback
* Fix casing in error messages
* Fix merge errors
* Fix locking bugs
* Add test file for testing path_restore in Transit backend. Fails because 'force' is not implemented yet
* initial implementation of 'force', to force restore of existing transit key atomically
Update AWS Auth backend to use TypeHeader for iam request headers
- Remove parseIamRequestHeaders function and test, no longer needed with new TypeHeader
- Update AWS auth login docs
* Performance Standby Nodes guide
* Added a link in the Vault HA guide
* Added links
* Clarified the node selection info
* Incorporated feedback
* Added 'when the Enterprise license includes this feature'
* Fixed the label: server 8 -> VM8
* Incorporated the feedback
This will cause them to be removed even if they have not expired yet,
whereas before it would simply leave them in the store until they were
expired, but remove from revocation info.
