New HTTP endpoint for creating verifiable credentials

Closes #15

See merge request eclipse/xfsc/tsa/signer!12

Some unit tests start clean and create new signer service instance
for every test case. In order for all test cases to reuse a common
caching document loader, it's injected as dependency to the signer.

All this is needed because recently W3C introduced a rate limiter
on their web site and JSONLD context pages, and unit tests fail if
too many requests for resolving contexts are made in short periods
of time.

The service now supports multiple proofs on VC and VP,
both for creating and verifying them.
