Condense output when multiple tags are created

[aguschin]

If assign created a version, you'll get this long output:

$ gto assign classifier \
		--repo $REPO \
		--version v0.0.2
		--stage dev 
Created git tag 'classifier@v0.0.2' that registers version
Running `git push origin classifier@v0.0.2`
Successfully pushed git tag classifier@v0.0.2 on remote.
Created git tag 'classifier#dev#1' that assigns stage
Running `git push origin classifier#dev#1`
Successfully pushed git tag classifier#dev#1 on remote.

Would be more friendly to get something like:

$ gto assign classifier \
		--repo $REPO \
		--version v0.0.2
		--stage dev 
Created git tag 'classifier@v0.0.2' that registers version
Created git tag 'classifier#dev#1' that assigns stage
Running `git push origin classifier@v0.0.2 classifier#dev#1`
Successfully pushed git tags on remote.
