make timeout configurable

[vrabbi]

can you add a timeout field for apply of a kubectl_manifest? i think its currently hardcoded and certail resources we are dealing with when waiting for a condition is exceeding this timeout making it not work

mm, I will have a look. It might be set up on the terraform level and not on the provider.

Terraform has the concept of timeouts built in, but you should be able to either override or augment this through the resource (or data source) API as the Helm provider does.
