infra/vsts_agent_linux_startup.sh: warm up local caches, purge old ag…

…ents (digital-asset#438) Warm up local caches by building dev-env and current daml master This is allowed to fail, as we still want to have CI machines around, even when their caches are only warmed up halfway. Afterwards, we purge old agents that might still be around, that didn't unregister themselves This depends on digital-asset#402 to be merged, as otherwise purge_old_agents.py can't be found obviously.
