CNTRLPLANE-216: Add KubeAPIExteralName api

[jparrill]

This new API autogenerate a new kubeconfig based on a desired url and managed by HCP.

What this PR does / why we need it:
The current implementation of HCP to define the KAS address is using the ServicePublishingType, where you can define a hostname and that, will customize the API and API-INT interfaces where all the kubeconfigs (excepts the ones pointing to local) are pointing to. This makes the customization rigid and customers are asking for more flexibility.

This PR adds a new API which creates a new Kubeconfig (certificate based) pointing to the desired address. With this new API you can:

• Modify the address day-1 and day-2 without affectation of the DataPlane (No rollout expected)
• Generation of a new Kubeconfig based on certificates (managed by HCP)
• The HC and HCP are in sync about this new Kubeconfig and reported in the status as customKubeconfig
• The target of this new API are the scenarios of Public and PublicAndPrivate

⚠️ IMPORTANT! The external DNSs URL where you plan to point to and you will specify it in this new API, should be properly configured in order to makes this work.

In response to this:

This new API changes the value of the Kubeconfig External URL to points to your desired one

What this PR does / why we need it:
HostedControlPlanes does not follows the separation of API and API-INT as OCP Standalone does. This PR includes a new API called KubeAPIExteralName which takes the desired name for the external KubeAPI Server name.

To have in mind:

• This can be changed day-0 or day-2
• This will not cause a nodepool rollout
• This will generate a new Kubeconfig called apiext-admin-kubeconfig
• This Kubeconfig should be bubbled up into HC namespace too

HostedControlPlanes does not follows the separation of API and API-INT

Can we elaborate on this? Which topologies is this use case targeting: privateAndPublic, private, public?
For privateAndPublic we do have decouple internal and external urls routing to kas, so what's this solving?
Seems the PR is effectively implementing a kubeconfig autogeneration using a passed through URL, let's make sure that's clearly stated in the PR desc and API docs, also let's clarify how this is planned to be consumed and that consumption solves the driving rfe.
