This replaces the previous `role_arn` with a block which looks like
this:
```
provider "aws" {
// secret key, access key etc
assume_role {
role_arn = "<Role ARN>"
session_name = "<Session Name>"
external_id = "<External ID>"
}
}
```
We also modify the configuration structure and read the values from the
block if present into those values and adjust the call to AssumeRole to
include the SessionName and ExternalID based on the values set in the
configuration block.
Finally we clean up the tests and add in missing error checks, and clean
up the error handling logic in the Auth helper functions.
This commit enables terraform to utilise the assume role functionality
of sts to execute commands with different privileges than the API
keys specified.

* Skip IAM/STS validation and metadata check
* Skip IAM/STS identity validation - For environments or other api
implementations where there are no IAM/STS endpoints available, this
option lets you opt out from that provider initialization step.
* Skip metdata api check - For environments in which you know ahead of
time there isn't going to be a metadta api endpoint, this option lets
you opt out from that check to save time.
* Allow iam/sts initialization even if skipping account/cred validation

* Split out skip of IAM validation into credentials and account id

Version 1.3.1 deprecates use of `session.New()` in favour of
`session.NewSession()`, which also returns an error. This commit updates
the various call sites previously making use of `session.New()`.
