Generate an access key pair + security token for a specific role.
`
const pathSTSHelpDesc = `
This path will generate a new, never before used key pair + security token 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/sts/deploy" would generate access keys for the "deploy" role.
Note, these credentials are instantiated using the AWS STS backend.
The access keys will have a lease associated with them. The access keys
can be revoked by using the lease ID.
