Add hidden command to install the guest components

[afbjorklund]

This will install the lima-guestagent in the instance.

It will install nerdctl-full.tgz, if it has been enabled.

Normally this is done by cidata, during the first boot...

Here it is just using scp and ssh, for convenience.

Workaround for:

• Generic/External internal driver for all OS #2000

Something like:

INFO[0094] Installing /tmp/nerdctl-full.tgz in /usr/local 

It could have been a shell script.

But the code "knows" the paths...

[afbjorklund]

This command is a replacement for cidata.iso, when not using cloud-init for provisioning.

It also saves having a copy of the lima-guestagent and nerdctl-full.tgz, in the instance dir...

44K /home/anders/.lima/raspberrypi/

The --rsync flag is mostly a workaround for slow networks and slow machines, and optional.

[afbjorklund]

Rebased to lima v0.21.0, tested with nerdctl-full v1.7.5

[afbjorklund]

• Make the gzipped tarball output rsyncable for poor man's delta updates containerd/nerdctl#2920

[AkihiroSuda]

Thanks, and sorry for taking too long time to review

[AkihiroSuda]

Could you rebase to rerun the CI?

[AkihiroSuda]

ping @afbjorklund

[afbjorklund]

You can scope this out from the 0.22 release

[afbjorklund]

Changed to use temporary filenames for the copy, and remove them after installation.

This makes the rsync flag less useful, so we need some other method to skip updates...

[afbjorklund]

Removed the rsync flag, since it is now useless when using temporary filenames.

[afbjorklund]

This command is only needed when not using cidata.iso, so it goes together with PR #2000 (but it is stand-alone)

The user would still have to start the guestagent and containerd services, the command only installs the binaries.

[AkihiroSuda]

Thanks
