Upgrade to Davrods 4.3

[mikkonie]

Together with bihealth/irods-docker#16 and bihealth/sodar-docker-compose#34, this needs to be updated as well.

Tasks

• Update image to Ubuntu (see Upgrade image to Ubuntu #6)
• Upgrade to latest Davrods 4.3 release
• Ensure PAM logins work
• Ensure token logins work (see Increase password length limit #4)
• Update default build version in build.sh and README.md

The lastest (pre-?) release of Davrods for iRODS 4.3 is 4.3.0_1.5.0. I'll have to see how well it works with iRODS 4.3.3

Since that release there doesn't seem to have been any work for iRODS 4.3 support. However, I noticed this comment for two weeks ago stating that they would be continuing this work "soon".

I should maybe have checked on the status of Davrods dev sooner when I restarted my work on iRODS 4.3 upgrades..

Update: Then again rit-davrods has been updated for iRODS 4.3.2. Perhaps this will work.
