Add OIDC middleware

[mantas-sidlauskas]

Adding OpenID Connect (OIDC) middleware.

• The OIDC middleware allows users to authenticate using external identity providers (IdPs) providers. (Okta, AWS Cognito, Auth0, Google, etc)
• Configuration can be passed as env variables or using dedicated configuration file.
• Middleware will check for token exp time to avoid situation when expired token is sent to Cadence Server

LGTM, can you please add an example usage in the readme file

I'm planning to add README.md in the next PR where I will check in code if this middleware has to be enabled.
