OAuth2 failed to fetch token error using 1.11.0

[displague]

When accessing only the Equinix Metal resources, it is typical to not have provider settings client_id, client_secret, or token defined.

In Equinix Provider version 1.11.0, when these values are not defined the following error is returned:

Error: oauth2: failed to fetch token: Post "https://api.equinix.com/oauth2/v1/token": oauth2: error when acquiring token: code: S1006, message Login Failure, please try again.

This appears to be caused by additional OAuth2 Token processing introduced in #230. The Fabric API client should not attempt to exchange a Client ID and Client Secret for an OAuth2 access token when the Client ID and Client Secret are not defined.

Workarounds:

• Revert and/or pin version 1.10 of the provider
• export EQUINIX_API_TOKEN="-"
