Port is not allowed to be int anymore

[semnell]

What happened:
Helm chart 1.16.1 broke compatibility with older values as before we could use integers as port values for readiness and liveness probes

What you expected to happen:

Port: 8888 is valid in liveness or readiness probe config

How to reproduce it (as minimally and precisely as possible):

Set port as int instead of string (which is valid in kubernetes)

Anything else we need to know?:

Environment:

• External-DNS version (use external-dns --version): N.A.N.
• DNS provider: Infoblox
• Others:

@semnell out of interest why are you using the port number instead of the name?

[semnell]

We're uing a custom provider using webhook and it uses a non standard port. We used to be able to just define the port but now we're unable to do so after te validation was added.

@semnell do you mean the probes on the webhook rather than the controller (default container)? If so could you update the issue and PR to make this clear?
