As we're trying to move away from gob for serialising data over the
wire, this commit adds the capability for Packer to pick dynamically
between gob or protobuf for the serialisation format to communicate with
plugins.
As it stands, if all the plugins discovered are compatible with
protobuf, and we have not forced gob usage, protobuf will be the
serialisation format picked.
If any plugin is not compatible with protobuf, gob will be used for
communicating with all the plugins that will be used over the course of
a command.

The SDK's Ui interface has had some additions recently for supporting
format-strings and their arguments as paramereters to Say, Ask and
Error.
These changes to the interface means that all the implementations of
that interface need to match the definition, so in this case the
implementations we had in packer/ui.go need to be updated to support
those functions.
This change addresses vulnerabilities reported by govulncheck

The version of the golang.org/x/net we used (v0.8.0), is vulnerable to a
rendering issue, potentially escaping text that should not be, which can
enable other attacks then.
Packer itself is not vulnerable to the CVE as we don't render web pages,
but security checks do point it as an issue, so we fix it by updating
the dependencies.
CVE refrerence: GO-2023-1988
* Update external plugin documentation source
The Parallels plugin for Packer is now maintained by the Parallels team, under
their respective GitHub org. This changes updates the source address for
the external plugin that should be used for pulling new plugin
documentation.
* Removed packer-plugin-parallels for list of vendored plugins
This step removes community plugins from the Packer binary release. These plugins are being maintained and released independently of Packer and have become out of date. To ensure users are using the latest version of the plugins they are being removed in favor of the external plugin installation processes.
This change removes a set of plugins that have not been updated in a while. These
plugins have been archived for some time now. Users wishing to continue using these plugins
should use the `packer plugins install` or `packer init` commands to install the external plugin.
* Remove profitbricks plugin
* Remove oneandone plugin
The following plugins have been unmaintained for some time now, and their
upstream cloud provider has consolidate the services. These plugins
will continue to be available to Packer via direct installation using
packer init or the packer plugins install command. But they will no longer
be bundled with Packer.
The Digital Ocean plugin is now maintained and released by the Digital Ocean team.
To ensure users are downloading the latest available version the plugin will nolonger
be bundled with Packer.
* Update external plugin documentation source
The UCloud plugin for Packer is now maintained by the UCloud team, under
their respective GitHub org. This changes updates the source address for
the external plugin that should be used for pulling new plugin
documentation.
* Remove packer-plugin-ucloud from vendored plugins.
* Update external plugin documentation source
The Linode plugin for Packer is now maintained by the Linode team, under
their respective GitHub org. This changes updates the source address for
the external plugin that should be used for pulling new plugin
documentation.
* Removed packer-plugin-linode for list of vendored plugins
The Linode plugin for Packer is now maintained by the Linode team, under
their respective GitHub org. This changes removes Linode from the vendored plugins
lists.
