Releases 0.38.0 through 0.38.25 recorded the ENV file migration and deliberately left the file at the old path, so 0.38.26 treating a leftover file as a hand-edit replayed the environment as it stood at that upgrade over every `config:set` and `config:unset` made since, reinstating variables and secrets that had been deliberately unset. A file found at the old path once its migration is on record is no longer imported: it is removed when it agrees with the current config, and is otherwise moved aside to `ENV.migrated` with the keys it disagrees on named in a warning. That warning now reaches the operator during an upgrade rather than being swallowed, which is why the overwrite went unreported.
Install steps run in alphabetical order of the enabled plugin directory, so `apps`, `builder`, and `checks` read an app's environment before the `config` plugin had moved the `ENV` file to its new location. The read came back empty, so their deprecated `DOKKU_*` variables were never migrated to the matching plugin property and were never unset, with nothing reported either way: `dokku config:show` kept listing the variable while the plugin behaved as though it were unset. The relocation now runs before any deprecated variable is read, whatever the install order, and each old file is removed as soon as it has been drained rather than on a later install, which also covers the global file that was never removed at all. A file that reappears at the old path can only have been written by hand, so it is merged in with a warning naming its keys instead of being discarded.
Chart property names containing `/` failed because per-key flat-file storage interpreted the slash as a filesystem path separator, and any move to line-based storage would silently truncate multi-line values. A new `PropertyMap*` helper family in `common` persists each map as a single JSON file so both `/` in keys and `\n` in values round-trip losslessly. Chart overrides move to `chart-overrides.<chart>` and an idempotent `TriggerInstall` migration rewrites any legacy `chart.<chart>.<key>` files into the new layout. The deprecated `scheduler-k3s:set --global chart.*` form is rerouted through the same map storage so it does not silently orphan writes. Closes#8717.
The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

Not all properties can be set globally, and the "appName" in the global case is currently defaulted to `--global`. This is okay because domain label names cannot start with hyphens, and all app names must be valid domain label names.
Rather than reimplementing the property functions in two different languages - and potentially having compatibility issues - standardize on golang for the implementation through the use of a generated binary.
This also implements all the list functions for use with shell-based plugins.
Note that the interface to the prop binary is experimental, and it should not be used directly.
- use a plugin trigger to see whether we should bind to all interfaces
- create a generic way of setting properties for a plugin
- migrate proxy-enabled to the new network property "bind-all-interfaces"
- add network:set subcommand
