Conjur prints its version upon startup

[orenbm]

When we start the Conjur server, it prints the following to the log:

authn-local is listening at /run/authn-local/.socket

It will be very helpful for our supportability if the server will print also the version on Conjur. More importantly, this log message should be printed in DAP so it will help us to indicate the Conjur version inside DAP.

DoD:

• Conjur version is logged upon startup of Conjur OSS
• Conjur version is logged upon startup of DAP
