eda8ea154a runtime: Gofmt fixes
- Mostly blank lines after `+build` -- see
  https://pkg.go.dev/go/build@go1.14.15 -- this is, to date, enforced by
  `gofmt`.
- 1.17-style go:build directives are also added.
- Spaces in govmm/vmm_s390x.go

5e119e90e8 virtcontainers: Rename the Network structure fields and methods
We are converting the Network structure into an interface, so that
different host OSes can have different networking implementations for
Kata.
One step into that direction is to rename all the Network structure
fields and methods to something that is less Linux networking namespace
specific. This will make the Network interface naming consistent.

4c2883f7e2 vc: hypervisor: remove dependency on persist API
Today the hypervisor code in vc relies on persist pkg for two things:
1. To get the VM/run store path on the host filesystem,
2. For type definition of the Load/Save functions of the hypervisor
   interface.

For (1), we can simply remove the store interface from the hypervisor
config and replace it with just the path, since this is all we really
need. When we create a NewHypervisor structure, outside of the
hypervisor, we can populate this path.

For (2), rather than have the persist pkg define the structure, let's
let the hypervisor code (soon to be pkg) define the structure. persist
API already needs to call into hypervisor anyway; let's allow us to
define the structure.

We'll probably want to look at following similar pattern for other parts
of vc that we want to make independent of the persist API.

In doing this, we started an initial hypervisors pkg, to hold these
types (avoid a circular dependency between virtcontainers and persist
pkg). Next step will be to remove all other dependencies and move the
hypervisor specific code into this pkg, and out of virtcontaienrs.

e61f5e2931 runtime: Show socket path in kata-env output
Display a pseudo path to the sandbox socket in the output of
`kata-runtime env` for those hypervisors that use Hybrid VSOCK.

The path is not a real path since the command does not create a sandbox.
The output includes a `{ID}` tag which would be replaced with the real
sandbox ID (name) when the sandbox was created.

This feature is only useful for agent tracing with the trace forwarder
where the configured hypervisor uses Hybrid VSOCK.

Note that the features required a new `setConfig()` method to be added
to the `hypervisor` interface. This isn't normally needed as the
specified hypervisor configuration passed to `setConfig()` is also
passed to `createSandbox()`. However the new call is required by
`kata-runtime env` to display the correct socket path for Firecracker.
The new method isn't wholly redundant for the main code path though as
it's now used by each hypervisor's `createSandbox()` call.

62baa48ef5 virtcontainers: fc: parse vcpuID correctly
In getThreadIDs(), the cpuID variable is derived from a string that
already contains a whitespace. As a result, strings.SplitAfter returns
the cpuID with a leading space. This makes any go variant of string to int
fail (strconv.ParseInt() in our case). This patch makes sure that the
leading space character is removed so the string passed to
strconv.ParseInt() is "CPUID" and not " CPUID".

This has been caused by a change in the naming scheme of vcpu threads
for Firecracker after v0.19.1.

9256e590dc shutdown: Don't sever console watcher too early
Fixed logic used to handle static agent tracing.

For a standard (untraced) hypervisor shutdown, the runtime kills the VM
process once the workload has finished. But if static agent tracing is
enabled, the agent running inside the VM is responsible for the
shutdown. The existing code handled this scenario but did not wait for
the hypervisor process to end. The outcome of this being that the
console watcher thread was killed too early.

Although not a problem for an untraced system, if static agent tracing
was enabled, the logs from the hypervisor would be truncated, missing the
crucial final stages of the agents shutdown sequence.

The fix necessitated adding a new parameter to the `stopSandbox()` API,
which if true requests the runtime hypervisor logic simply to wait for
the hypervisor process to exit rather than killing it.

Fixes: #1696.
