ADFS with automatic support of cert rollover

[kratzerph]

Intro

Thanks for this great app! Keep on rocking!

Steps to reproduce

1. Our ADFS holds 2(primary+secondary) decryption/signing certs. Rollover works with a few of fed. apps, e.g. cisco webex. Looks like nextcloud does not support this or we did not figure out how to get this to work. The process of exchanging certs/token is explained on: https://itpro.outsidesys.com/2017/10/14/adfs-token-certificate-rollover/

Expected behaviour

Nextcloud can rollover certs/tokens if they getting close to expire

Actual behaviour

Certs does not get automatically rollovered
