This commit migrates containerd/protobuf from github.com/gogo/protobuf
to google.golang.org/protobuf and adjust types. Proto-generated structs
cannot be passed as values.
Fixes#6564.

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Closes#1862
This adds a new rpc to the introspection service to provide server
information with a generated UUID that is done on demand and the os and
arch of the server.

Since Go 1.7, context is a standard package, superceding the
"x/net/context". Since Go 1.9, the latter only provides a few type
aliases from the former. Therefore, it makes sense to switch to the
standard package.

minor fixups to remove extra changes done by goimports):

We move from having our own generated version of the googleapis files to
an upstream version that is present in gogo. As part of this, we update
the protobuf package to 1.0 and make some corrections for slight
differences in the generated code.
The impact of this change is very low.

This linter checks for unnecessary type convertions.
Some convertions are whitelisted because their type is different

Since these are registered and the interface is what matters, these
Service types do not need to be exported.

With this change, we integrate all the plugin changes into the
introspection service.
All plugins can be listed with the following command:
```console
$ ctr plugins
TYPE ID PLATFORM STATUS
io.containerd.content.v1 content - ok
io.containerd.metadata.v1 bolt - ok
io.containerd.differ.v1 walking linux/amd64 ok
io.containerd.grpc.v1 containers - ok
io.containerd.grpc.v1 content - ok
io.containerd.grpc.v1 diff - ok
io.containerd.grpc.v1 events - ok
io.containerd.grpc.v1 healthcheck - ok
io.containerd.grpc.v1 images - ok
io.containerd.grpc.v1 namespaces - ok
io.containerd.snapshotter.v1 btrfs linux/amd64 error
io.containerd.snapshotter.v1 overlayfs linux/amd64 ok
io.containerd.grpc.v1 snapshots - ok
io.containerd.monitor.v1 cgroups linux/amd64 ok
io.containerd.runtime.v1 linux linux/amd64 ok
io.containerd.grpc.v1 tasks - ok
io.containerd.grpc.v1 version - ok
```
There are few things to note about this output. The first is that it is
printed in the order in which plugins are initialized. This useful for
debugging plugin initialization problems. Also note that even though the
introspection GPRC api is a itself a plugin, it is not listed. This is
because the plugin takes a snapshot of the initialization state at the
end of the plugin init process. This allows us to see errors from each
plugin, as they happen. If it is required to introspect the existence of
the introspection service, we can make modifications to include it in
the future.
The last thing to note is that the btrfs plugin is in an error state.
This is a common state for containerd because even though we load the
plugin, most installations aren't on top of btrfs and the plugin cannot
be used. We can actually view this error using the detailed view with a
filter:
```console
$ ctr plugins --detailed id==btrfs
Type: io.containerd.snapshotter.v1
ID: btrfs
Platforms: linux/amd64
Exports:
root /var/lib/containerd/io.containerd.snapshotter.v1.btrfs
Error:
Code: Unknown
Message: path /var/lib/containerd/io.containerd.snapshotter.v1.btrfs must be a btrfs filesystem to be used with the btrfs snapshotter
```
Along with several other values, this is a valuable tool for evaluating the
state of components in containerd.
