Add a version option to ots-cli command line

[mshedsilegx]

Can we please add a --version option to ots-cli, so it displays the version number; similar to what the ots server binary does.

Did not add an option but a sub-command which is the more used behavior for Cobra command binaries:

# ./ots-cli version
ots-cli dev

[mshedsilegx]

Great. Shouldn't the CLI version match the main OTS binary, ie for example: 1.11.1-f2a7af3

[Luzifer]

It will. The same version string will be baked in during release compile. dev is the fallback when no version is baked in (like when installing through go install or go build in a checkout). Have a look at the https://github.com/Luzifer/ots/blob/master/ci/build.sh#L20-L24 how the version is baked in.
