a19263e58d agent/protocols: Remove unneeded import from oci.proto
oci.proto imports "google/protobuf/wrappers.proto", but doesn't appear to
use it, which causes a warning from protoc when we compile it.  Remove the
import to fix the warning.

In PR 1079, CleanupContainer's parameter of sandboxID is changed to VCSandbox, but at cleanup,
there is no VCSandbox is constructed, we should load it from disk by loadSandboxConfig() in

annotations: Improve asset annotation handling

e82c9daec3 annotations: Improve asset annotation handling
Make `asset.go` the arbiter of asset annotations by removing all asset
annotations lists from other parts of the codebase.

This makes the code simpler, easier to maintain, and more robust.

Specifically, the previous behaviour was inconsistent as the following
ways:

- `createAssets()` in `sandbox.go` was not handling the following asset
  annotations:

    - firmware:
      - `io.katacontainers.config.hypervisor.firmware`
      - `io.katacontainers.config.hypervisor.firmware_hash`

    - hypervisor:
      - `io.katacontainers.config.hypervisor.path`
      - `io.katacontainers.config.hypervisor.hypervisor_hash`

    - hypervisor control binary:
      - `io.katacontainers.config.hypervisor.ctlpath`
      - `io.katacontainers.config.hypervisor.hypervisorctl_hash`

    - jailer:
      - `io.katacontainers.config.hypervisor.jailer_path`
      - `io.katacontainers.config.hypervisor.jailer_hash`

- `addAssetAnnotations()` in the `oci` package was not handling the
  following asset annotations:

    - hypervisor:
      - `io.katacontainers.config.hypervisor.path`
      - `io.katacontainers.config.hypervisor.hypervisor_hash`

    - hypervisor control binary:
      - `io.katacontainers.config.hypervisor.ctlpath`
      - `io.katacontainers.config.hypervisor.hypervisorctl_hash`

    - jailer:
      - `io.katacontainers.config.hypervisor.jailer_path`
      - `io.katacontainers.config.hypervisor.jailer_hash`

This change fixes the bug where specifying a custom hypervisor path via an
asset annotation was having no effect.

Fixes: #1085.

6f52179ce4 annotations: Add unit test for regexpContains function
James O.D Hunt: "But also, regexpContains() and
checkPathIsInGlobList() seem like good candidates for some unit
tests. The "look" obvious, but a few boundary condition tests would be
useful I think (filenames with spaces, backslashes, special
characters, and relative & absolute paths are also an interesting
thought here)."

There aren't that many boundary conditions on a list with regexps,
if you assume the regexp match function itself works. However, the
tests is useful in documenting expectations.

7c6aede5d4 config: Whitelist hypervisor annotations by name
Add a field "enable_annotations" to the runtime configuration that can
be used to whitelist annotations using a list of regular expressions,
which are used to match any part of the base annotation name, i.e. the
part after "io.katacontainers.config.hypervisor."

For example, the following configuraiton will match "virtio_fs_daemon",
"initrd" and "jailer_path", but not "path" nor "firmware":

  enable_annotations = [ "virtio.*", "initrd", "_path" ]

The default is an empty list of enabled annotations, which disables
annotations entirely.

If an anontation is rejected, the message is something like:

  annotation io.katacontainers.config.hypervisor.virtio_fs_daemon is not enabled

f047fced0b config: Use glob instead of regexp to match paths in annotations
When filtering annotations that correspond to paths,
