Make clusterctl cert-manager timeout configurable

[ncdc]

User Story

As a developer using the clusterctl library, I would like to be able to specify a custom timeout for waiting for cert-manager to be available, as the default hard-coded 10 minute value might not be enough if my internet connection is slow.

@fabriziopandini How do we set other timeouts today? Environment variables, flags?

[ncdc]

MVP for me is library-only for an API consumer. Bonus is a flag or env var.

The simplest implementation will be using envvars, like e.g we are doing for the overrideFolder.
Library only requires an interface change, soI highly raccomand to tackle this with #2597 and #2659

@fabriziopandini I was trying to implement this by adding a flag to the init command, do you think that is better or doing a env var?

[ncdc]

Ok, env var is fine for now 😄
