Add tags as resource tags in the launch template used to request spot instances

* move maps of plugins back in core

* go mod vendor

* more fixes

* fix imports

* Update core_test.go

* fix build

* more fixes

* more fixes

* up vendors after fixing sdk

* Update post_processor_mock.hcl2spec.go

* Leave implementatino of MapOf in the sdk for plugi tests

Other wise use the interface

* go mod tidy

* add MapOfDatasource type too

Use run_tags (resp run_volume_tags) to tags intances (resp volumes) created from the spot instance launch template

fix regression in return code checking in vsphere postprocessor. this…

Fix for vnc_min_port set to value greater then 5900 potentially causing packer to be unable to connect to QEMU 

* prepare to move to vercel hosting

* add html extension handling

* add back netlify files for transition

It is being printed after it is created so we need to mock it to prevent
a nil pointer dereference when the tests are run with the launch
template create request is mocked.

According to the APIReference:
<https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_LaunchTemplateTagSpecificationRequest.html>,
the resource types `instance` and `volume` support tagging on creation.
It is useful to add the spot tags here as it should be more reliable
than tagging them after the spot request is fulfilled as we currently
do.

Check to make sure that the max and min VNC ports be below 65535 in
config.

* Set the QEMU builder vnc_port_min to have a minimum value of 5900,
  with updated documentation to explain why.

* Changed output messages so that the correct port is listed in packer's
  messaging to the user.

LONGER DESCRIPTION

If vnc_min_port is set to anything above 5900, then packer will fail to
connect via VNC to the QEMU instance. This is due to how QEMU parses
the port for listening to VNC:

   host:d
               TCP connections will only be allowed from host on
               display d.  By convention the TCP port is 5900+d.

Previously the calculation for the port was vncPort - VNCPortMin,
however this will result in an incorrect port being displayed in
packer's messages and potentially packer being unable to connect via VNC
to the host.

For example if vnc_port_min=5990 nad vnc_port_max=5999:

```
Looking for available port between 5990 and 5999 on 0.0.0.0
Found available port: 5996 on IP: 0.0.0.0
Found available VNC port: 5996 on IP: 0.0.0.0
[....]
==> Starting VM, booting disk image
     view the screen of the VM, connect via VNC without a password to
     vnc://0.0.0.0:6
```

This will cause QEMU to set the listening port to 5906 while packer's
VNC client is attempting to connect to 5996.

I am a touch concerned as this commit undoes pull request #9905
(specfically commit 7335695c), but I am also confused as to how he was
able to get QEMU to get a VNC listening port below 5900, as examining
QEMU's git history has shown that this behavior has been in since at
least 2017, probably older.

Hopefully the more explicit error messaging and documentation can make
it clear why this is being undone.

allow plugins with registered items with name from plugin.DEFAULT_NAME string constant to be passthroughs to the plugin binary suffix
