The database migrations for IDEA event database *mentat_events* are now implemented. I have moved this issue to the next release, because there is code already merged in the current development branch that depended performing the migrations on target system. It was a choice of either removing that commit, or going forward with implementation. I have decided to implement it immediately, because this issue is blocking many more features.

The implementation is again based on Alembic tool, which is already being used for migrations on mentat_main metadata database. It is however separatelly configured instance, merging both instances into single one would require considerably more amount of research and work.

I have also updated accordingly manual pages regarding installation and upgrading. Very important bit of information was stamping the database with latest migration revision after clean installation.

Currently focus of this section is Mentat system health monitoring. (Redmine issue: #4222,#3361)

With the addition of database migration tools the steps for successfull upgrade of Mentat system within the 2.x series had to be documented. (Redmine issue: #4252)

Improved documentation related to installation, migration and quickstart overview based on feedback from users installing the system.

There is a lots of hidden work here in this commit. To make the installation process even more simple, we have prepared three Ansible roles available via official Ansible Galaxy site, that can very quickly install and configure Mentat system. (Redmine issue: #3361,#3387)

Implemented *reinit-main* command for main database schema reinitialization. Implemented *fixtures-add* and *fixtures-remove* command for inserting respectively deleting demonstration data objects (user accounts, groups, filters and networks). This will enable use to make demonstration isntallations more easy and smooth. (Redmine issue: #3383,#3387)

There are two Apache example configurations now, first is an example for Shibboleth SSO authentication, second is an example for Basic authentication. Using these two examples (especially the latter) it is possible to very quickly set up demonstration installation. The installation page was updated accordingly to reflect new installation options. (Redmine issue: #3387,#3361)

Enhanced section about installation, added new section about migration (based on experience from installation on new server). (Redmine issue: #3361)
