certificates/authority/tls_test.go
Mariano Cano c7f226bcec
Add support for renew when using stepcas 
It supports renewing X.509 certificates when an RA is configured with stepcas.
This will only work when the renewal uses a token, and it won't work with mTLS.

The audience cannot be properly verified when an RA is used, to avoid this we
will get from the database if an RA was used to issue the initial certificate
and we will accept the renew token.

Fixes #1021 for stepcas
