caddy-frontend: Implement KeDiFa SSL information
Use KeDiFa to store keys, and transmit the url to the requester for master and slave partitions. Download keys on the slave partitions level. Use caucase to fetch main caucase CA. kedifa-caucase-url is published in order to have access to it. Note: caucase is prepended with kedifa, as this is that one. Use kedifa-csr tool to generate CSR and use caucase-updater macro. Switch to KeDiFa with SSL Auth and updated goodies. KeDiFa endpoint URLs are randomised. Only one (first) user certificate is going to be automatically accepted. This one shall be operated by the cluster owner, the requester of frontend master partition. Then he will be able to sign certificates for other users and also for services - so each node in the cluster. Special trick from https://security.stackexchange.com/questions/74345/provide-subjectaltname-to-openssl-directly-on-command-line is used for one command generation of extensions in the certificate. Note: We could upgrade to openssl 1.1.1 in order to have it really simplified (see https://security.stackexchange.com/a/183973 ) Improve CSR readability by creating cluster-identification, which is master partition title, and use it as Organization of the CSR. Reserve slots for data exchange in KeDiFa.
