Add endpoint for getting identity provider info with metadata relevant for version 1 identity issuance

[eb-concordium]

Task description
Currently the endpoint /v0/ip_info contains public information about the identity providers together with some metadata. The metadata contains the url from where the identity issuance flow can be initiated.

Since there are now two identity issuance flows, a new endpoint /v1/ip_info should be added from where the metadata should contain the url for initiating the version 1 identity issuance flow. Furthermore it should contain the url for initiating recovery of an identity.
