On-disk credentials caching

[lauzadis]

Describe the feature

Implement support for on-disk credentials caching via the credential_cache and credential_cache_location environment variables.

Is your feature request related to a problem?

No.

Proposed Solution

Implement support according to the internal cross-SDKs specification. (disk-cache.md). Note: we already support in-memory caching via CachedCredentialsProvider, we just need to add support for on-disk caching.
