SPIKE: SAML implementation

[suzubara]

We need to implement SAML on the portal client in order to handle CAC authentication with Akamai. Research and determine the work needed in order to support SAML auth and pass user/session data into the application code.

Resources:

• https://nextjs.org/docs/authentication#bring-your-own-database
• http://www.passportjs.org/packages/passport-saml/
• https://confluence.di2e.net/pages/viewpage.action?spaceKey=AFCCE2&title=Akamai+and+GCDS+FAQ (Section labeled SSO Using SAML) (CAC auth required)
• https://github.com/andycmaj/nextjs-passport-session-auth

Since this is a spike issue, use it to do any kind of research or exploration to determine the best strategy forward, and create follow up issues when closing this issue to complete the work.
