Upgrade for ckan 2.10

Upgrade odsh extension to support ckan 2.10

• Requires a ckan db upgrade (2.10 added last_active column to user table)

• dcatap extension package clash (ckan 2.10 has pyparsing==3.0.7 while dcatde requires pyparsing<3, see this issue) --> fixed in 6.1.0

• Rework templates and CI
