Recategorise the projects currently grouped within Infrastructure Deployments

[MarckK]

Category request:

As @kostis-codefresh noted on #181, the current category of Infrastructure Deployments is a bit of a grab bag.

The current contents of this "category" are unrelated. Terraform is a CLI that implements infrastructure as code, Rancher is a cluster orchestration/management platform, Alibaba is a whole cloud provider, while Ketch is an application for Kubernetes deployments.

📯 Suggestions on recategorising these projects welcome below!

Now that the name of the category is changed, terraform should stay here. We should also add Pulumi and Crossplane in this category (not currently on the landscape).

Alibaba Cloud should move into a new category called "Cloud providers" or something similar along with Google, Azure, AWS, Digital Ocean and so on.

I have already talked about Ketch in #180

Rancher (and possibly Cycloid) should move into a new category called "Cloud/Application management" or something similar.

I am not familiar with the rest of the entries but looking at their web pages I would create a new category called PAAS or something similar.

IMHO the end result for this category (infrastructure deployments/automated provisioning) should contain very specific tools

• Terraform
• Pulumi
• Crossplane
• Cloudformation (AWS only)
• Google Cloud Deployment Manager (Google only)
• Azure resource manager ( Azure only)

As a general comment, (and I looked at the CDF FAQ) it is not clear to me if the landscape should include CD solutions that focus on applications only or include things that deal with infrastructure as well.
