[ci:component:github.com/gardener/terraformer:v2.2.0->v2.6.0]

[gardener-robot-ci-3]

*Release Notes:

Terraformer now copies Terraform's error outputs to `/terraform-termination-log` to make it available in the containers termination message for better analyzing and more readable error messages (e.g. in the Shoot status).

Terraform provider of Alicloud is upgraded to 1.121.2.

The following terraform provider plugins are updated:
- hashicorp/terraform-provider-google: 3.59.0 -> 3.62.0
- hashicorp/terraform-provider-google-beta: 3.59.0 -> 3.62.0

The aws provider has been downgraded from `3.32.0` to `3.18.0` due to issue with additionally required permission for the AWS accounts.

The golang has been updated to `1.16.2`, the alpine has been updated to `3.13.2`.

The following terraform provider plugins are updated:
- hashicorp/terraform-provider-aws: 3.18.0 -> 3.32.0
- hashicorp/terraform-provider-google: 3.27.0 -> 3.59.0
- hashicorp/terraform-provider-google-beta: 3.27.0 -> 3.59.0

The Terraformer now instantly removes its finalizer from the state `ConfigMap` if the state is empty and `destroy` is called. A separate Terraform `destroy` is not executed.

Terraformer will now publish an additional image without any pre-installed terraform plugins.

Provides support for the Equinix Metal provider, which replaces the Packet one
