Further improve the personal profile page

The #6 cycle in the GN4.3 incubator created a first version of a personal profile page for both Shibbileth idP as well as SimpleSAMLphp. Sprint demo result may be found here: https://docs.google.com/presentation/d/1GCJ5H50S0Zrm4xzLR-Hd5Vtaj-YpTqAfZHhtn-e6iHU/edit?usp=sharing
The sprint demo and also a similar demo at Internet2 TechEx yielded much positive response and a number of intresting suggestions for further improvements.
This activity proposes to continue the work on the profile page software:

• Create a version 2 of the MVP with additional features
• Further improve support for OIDC OP
