Tame Oauth Versions Save

Changed

• PR#72 update http -> 1.1.0.

Changed

• PR#67 upgraded ring from 0.16 -> 0.17.

Changed

• PR#66 replaced base64 with data-encoding.

Fixed

• PR#65 Use url safe base64 when decoding jwt claims from id tokens.

Fixed

• PR#63 Use correct base64 padding when decoding jwt claims from id tokens.

Added

• Support for id tokens, a new trait for this was added (IdTokenProvider) and implemented for all current token providers so both access tokens and id tokens can be fetched.
• Added is_*_provider methods to TokenProviderWrapper for asserting the inner type.
• PR#61 added debug implementations for all the providers (excludes sensitive data in the output).

Changed

• RequestReason::ScopesChanged was renamed to RequestReason::ParametersChanged
• PR#59 update outdated base64 dependency
• Moved the placement of the CachedTokenProvider on TokenProviderWrapper so that it wraps the outer type instead of the inner, that way the uncached provider can be accessed via .inner().

Fixed

• PR#57 Documentation improvements

Fixed

• PR#54 re-adds get_account_info to the outer ServiceAccountProvider implementation. It was accidentally removed in #51.

Changed

• PR#51 moved the token cache out of ServiceAccountProvider into a public type, and added a cached token provider that can wrap any other token provider. This wrapper now wrapps all the current gcp token providers, making them cached by default.
• PR#53 changed the cache lock from a Mutex into a RwLock.

Changed

• PR#47 removed the dependency upon chrono as it was overkill and brought in multiple security advisories and is only lightly maintained.

Added

• PR#40 added support for Metadata Server Auth so that you can obtain oauth tokens when running inside GCP. Thanks @boulos!
• PR#42 resolved #39 by adding support for the same default credentials flow as the the Go oauth2 implementation for Google oauth. This included adding support for EndUserCredentials. Thanks @boulos!
