Acsoo

------------------
- [IMP] more python 3 and Odoo 11 support
- [IMP] project template: build stage in gitlab-ci
- [IMP] project template: new style deploy / upgrade
(using checksum upgrades and click-odoo-upgrade script)
- [IMP] project template: enforce odoo-autodiscover>=2 and do not use it
for Odoo >= 11
- [IMP] add --dry-run option to acsoo tag and tag_requirements
- [IMP] make the list of places where tag_requirements can push
configurable
- [IMP] project template: on demand installation of acsoo and ssh-agent

------------------

- [IMP] python 3 support
- [IMP] preliminary Odoo 11 support

------------------
- [IMP] tag_requirements: fetch more aggressively; this solves the errors
trying to write ref with non existent object
- [IMP] tag: always tag requirements when doing acsoo tag
- [IMP] tag: tag requirements before tagging project, so if something fails
when tagging the requirements the project is not tagged and the release
build is not triggered.
- [ADD] addons: add --separator option (and fix tests that were not testing much)
- [IMP] addons: consider current dir as addons dir candidate
- [IMP] pylint: look for module to test in current dir by default, using the
same algorithm as ``addons list``
- [IMP] pylint: support python 3 style odoo/addons namespace (without __init__.py)

------------------
- [IMP] checklog: consider ignore lines starting with as comments
- [FIX] checklog: the previous release broke checklog color output

------------------
- [IMP] checklog: fail if no log record found in input

------------------
- [FIX] regression in acsoo release
