Generate an access key pair for a specific role.

|
|
This path will generate a new, never before used key pair for
|
|
accessing AWS. The IAM policy used to back this key pair will be
|
|
the "name" parameter. For example, if this backend is mounted at "aws",
|
|
then "aws/creds/deploy" would generate access keys for the "deploy" role.
|
|
|
|
The access keys will have a lease associated with them. The access keys
|
|
can be revoked by using the lease ID.
