Is your enhancement related to a problem? Please describe

There are several enhancements of ouath-proxy configuration (aka oauth-proxy.cfg) for kubernetes:

• To set pass_access_token to true (default value is false) to pass access token to upstream via "X-Forwarded-Access-Token"
• To set cookie_refresh to 1h0m0s to refresh the cookie when duration has elapsed after cookie was initially set.
• To add whitelist_domains to whitelist che domain (ie: .yourcompany.com)
• To add cookie_domains to set cookie domain to force cookies to (ie: .yourcompany.com)
• To add OAuthScope to Che Resource to allow users to configure Access Token Scope.
