Zarate/upgrade mint

fix doofinder/dfcommon#963

this is somehow complex to explain:

• if this PR is approved, then this doofinder/clickhousex doesn't depend on a git commit of Mint, but rather on a particular mint version. That would allow this project to be published
• so, if this PR is approved, then I'll publish this as a package with version 0.4.0 but I won't merge this branch just yet
• if this is published as a package, then stats project can depend on this package (currently, it depends on this project via git), and it can itself be publiished, therefore doofinder/dfcommon#963 can be achieved
• if stats , depending on clickhouse 0.4.0, which itself depends on mint 1.5.1 is ok, then I can merge this branch into the master, otherwise, to revert, stats should be reverted to depend on the git master of doofinder/clickhouse which itself (since we haven't merged the branch yet) depends on git 8... of mint

Only a question, We can't change to more up to date library like pillar?

I'm all for that. But I would do that after we stabilized things with clickhousex. When stats and dftasks works fine depending on this internal clickhousex hex package, I'd change it to pillar, because changing library probably means changing code a lot ...
