Changes from v2.4.0 to v2.5.0

• Verified with cloudfoundry/cf-deployment @ b70090f9237b5e24ab86410842b0288bcf6862f1.
• Verified with garden-runc-release v1.13.1.
• Verified with garden-windows-bosh-release v0.13.0.
• Verified with cflinuxfs2-release v1.203.0.

Significant changes

BBS API

• As a CF operator, I expect the BBS not to crash because it cannot find a valid ActualLRP

Container Placement

• As a CF operator, I expect to be able experimentally to opt Diego into retrying placement of a Task a limited number of times so that Task placement can be more resilient to transient drops in addressable capacity
• As a BBS API client, I expect to see placement errors and placement failure counts on Tasks so that I can understand why they are still Pending

SSH

• As a CF app developer, I expect to be able to create remote SSH tunnels to my app instances so that I can connect them to network resources local to my workstation
• As a CF operator, I expect the ssh_proxy's diego.ssh_proxy.uaa.port property to default to 8443 so that I do not have to supply it in my CF manifest
• As a CF Java developer, I expect the default CF SSH cipher suites, MACs, and key exchange algorithms to be compatible with the SSHJ client library so that I can use existing Java developer tooling against my CF deployment

Per-Instance Proxy (Experimental)

• As a CF operator, I expect to understand how the Envoy proxies consume memory resources under concurrent request load so that I can provision resources appropriately to support route-integrity improvements (in flight)
• As a CF operator, I expect to be able to run at least 250 container instances on my proxy-enabled Linux Diego cells so that my container density is not artificially limited

App Logging and Metrics

• As a Diego operator, I expect the cell rep API to report container metrics so that I can inspect these properties on-demand
