As newer versions of Consul are released, the minimum version of Envoy it supports as a sidecar proxy also gets bumped. Starting with the upcoming Consul v1.9.X series, Envoy v1.11.X will no longer be supported. Current versions of Nomad hardcode a version of Envoy v1.11.2 to be used as the default implementation of Connect sidecar proxy. This PR introduces a change such that each Nomad Client will query its local Consul for a list of Envoy proxies that it supports (https://github.com/hashicorp/consul/pull/8545) and then launch the Connect sidecar proxy task using the latest supported version of Envoy. If the `SupportedProxies` API component is not available from Consul, Nomad will fallback to the old version of Envoy supported by old versions of Consul. Setting the meta configuration option `meta.connect.sidecar_image` or setting the `connect.sidecar_task` stanza will take precedence as is the current behavior for sidecar proxies. Setting the meta configuration option `meta.connect.gateway_image` will take precedence as is the current behavior for connect gateways. `meta.connect.sidecar_image` and `meta.connect.gateway_image` may make use of the special `${NOMAD_envoy_version}` variable interpolation, which resolves to the newest version of Envoy supported by the Consul agent.
