add validation and migration for deprecated logentries driver

A validation step was added to prevent the daemon from considering "logentries"
as a dynamically loaded plugin, causing it to continue trying to load the plugin;

    WARN[2023-12-12T21:53:16.866857127Z] Unable to locate plugin: logentries, retrying in 1s
    WARN[2023-12-12T21:53:17.868296836Z] Unable to locate plugin: logentries, retrying in 2s
    WARN[2023-12-12T21:53:19.874259254Z] Unable to locate plugin: logentries, retrying in 4s
    WARN[2023-12-12T21:53:23.879869881Z] Unable to locate plugin: logentries, retrying in 8s

But would ultimately be returned as an error to the user:

    docker container create --name foo --log-driver=logentries nginx:alpine
    Error response from daemon: error looking up logging plugin logentries: plugin "logentries" not found

With the additional validation step, an error is returned immediately:

    docker container create --log-driver=logentries busybox
    Error response from daemon: the logentries logging driver has been deprecated and removed

A migration step was added on container restore. Containers using the
"logentries" logging driver are migrated to use the "local" logging driver:

    WARN[2023-12-12T22:38:53.108349297Z] migrated deprecated logentries logging driver  container=4c9309fedce75d807340ea1820cc78dc5c774d7bfcae09f3744a91b84ce6e4f7 error="<nil>"

As an alternative to the validation step, I also considered using a "stub"
deprecation driver, however this would not result in an error when creating
the container, and only produce an error when starting:

    docker container create --name foo --log-driver=logentries nginx:alpine
    4c9309fedce75d807340ea1820cc78dc5c774d7bfcae09f3744a91b84ce6e4f7

    docker start foo
    Error response from daemon: failed to create task for container: failed to initialize logging driver: the logentries logging driver has been deprecated and removed
    Error: failed to start containers: foo

For containers, this validation is added in the backend (daemon). For services,
this was not sufficient, as SwarmKit would try to schedule the task, which
caused a close loop;

    docker service create --log-driver=logentries --name foo nginx:alpine
    zo0lputagpzaua7cwga4lfmhp
    overall progress: 0 out of 1 tasks
    1/1: no suitable node (missing plugin on 1 node)
    Operation continuing in background.

    DEBU[2023-12-12T22:50:28.132732757Z] Calling GET /v1.43/tasks?filters=%7B%22_up-to-date%22%3A%7B%22true%22%3Atrue%7D%2C%22service%22%3A%7B%22zo0lputagpzaua7cwga4lfmhp%22%3Atrue%7D%7D

    DEBU[2023-12-12T22:50:28.345201257Z] Calling GET /v1.43/nodes

So a validation was added in the service create and update endpoints;

    docker service create --log-driver=logentries --name foo nginx:alpine
    Error response from daemon: the logentries logging driver has been deprecated and removed
