In alpha the version printed is a hard-code string, now it has been removed.
What do you think if the console execute show hosts graph and get the version info implicitly?

how to get the version of the console itself? not the db.

it could be possible that the console's version is inconsistent with db.

./nebula-console --version could get the version of itself.

I could a local command like :version to print the version of console.

Seems that the version printed on welcome should be the version of the server, not the console.

how about print both console and db's version?
