* ci: always use the linux-pool
reduce the difference of environment between external and internal
contributions
* infra: tweak the linux cache warmup script
Don't share the same bazel cache directory with the disk cache, which is
something else. Be more specific about the target. Clean after yourself.
* infra: bump the linux agent disk to 200GB
avoid running out of disk space
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 #402 to be merged, as otherwise purge_old_agents.py
can't be found obviously.
