Cannot import EC2 launch template

[tlinhart]

What happened?

It's not possible to import EC2 launch template to Pulumi state due to validation errors.

Steps to reproduce

Following this guide, I tried to use pulumi import which issued these warnings:

$ pulumi import aws:ec2/launchTemplate:LaunchTemplate internal-services lt-xxxxx
Previewing import (internal-services-dev):
     Type                       Name                                               Plan       Info
     pulumi:pulumi:Stack        internal-services-internal-services-dev             
 =   └─ aws:ec2:LaunchTemplate  internal-services                                  import     3
 
Diagnostics:
  aws:ec2:LaunchTemplate (internal-services):
    warning: One or more imported inputs failed to validate. This is almost certainly a bug in the `aws` provider. The import will still proceed, but you will need to edit the generated code after copying it into your program.
    warning: aws:ec2/launchTemplate:LaunchTemplate resource 'internal-services' has a problem: expected metadata_options.0.http_protocol_ipv6 to be one of [disabled enabled], got . Examine values at 'LaunchTemplate.MetadataOptions.HttpProtocolIpv6'.
    warning: aws:ec2/launchTemplate:LaunchTemplate resource 'internal-services' has a problem: expected metadata_options.0.instance_metadata_tags to be one of [disabled enabled], got . Examine values at 'LaunchTemplate.MetadataOptions.InstanceMetadataTags'.
 
Do you want to perform this import?

After copy/pasting the generated code into Pulumi program and running pulumi up, I receive an error:

$ pulumi up
Previewing update (internal-services-dev):
     Type                        Name                                              Plan       Info
     pulumi:pulumi:Stack         internal-services-internal-services-dev                      1 err
 =   └─ aws:ec2:LaunchTemplate   internal-services                                 import     3
 
Diagnostics:
  aws:ec2:LaunchTemplate (internal-services):
    error: aws:ec2/launchTemplate:LaunchTemplate resource 'internal-services' has a problem: expected metadata_options.0.http_protocol_ipv6 to be one of [disabled enabled], got . Examine values at 'LaunchTemplate.MetadataOptions.HttpProtocolIpv6'.
    error: aws:ec2/launchTemplate:LaunchTemplate resource 'internal-services' has a problem: expected metadata_options.0.instance_metadata_tags to be one of [disabled enabled], got . Examine values at 'LaunchTemplate.MetadataOptions.InstanceMetadataTags'.
    error: Preview failed: one or more inputs failed to validate
    error: preview failed

Expected Behavior

As there seems to be no option to specify the corresponding options in either AWS console nor using AWS CLI, I'd need to bypass the Pulumi checks for matching inputs with the existing resource's values (while specifying enabled/disabled for the corresponding metadata options) or disable validations using pulumi up (while leaving the metadata options empty to match the existing resource's values).

Actual Behavior

Pulumi either reports a validation error when using the generated code or reports an inputs mismatch with existing resource's options.

Just a quick addition. I can work around the issue by exporting the stack, changing the corresponding resource's inputs and outputs and importing the stack back.
