Upgrade Guacamole deps 1.5.1

[tamirkamara]

What is being addressed

With Guacamole 1.5.* the base image of guacd has move to alpine which requires a bunch of changes in the bundle.

How is this addressed

• Update all Guacamole dependencies to 1.5.1 (base image, war, jar - although it's provided).
• Use apk to install OS dependencies including openjdk11 (which has previously been manually installed).
• Generate host RSA keys as those aren't generated automatically in alpine
• Update s6 run script for guacd as it changed location
• Update terraform binary and providers
