Support Timeout configuration options

[berney]

I'm also hitting #30 Error 409 - urn:acme:error:malformed - Certificate already revoked which seems to occur after a destroy has timed out after 3 minutes. I'm consistently hitting this. As well as fixing #30 can you add support for configurable timeouts https://www.terraform.io/docs/configuration/resources.html#timeouts

Hitting this every time I make an update as well. Using the aws route53 dns configuration.

After re-running the cert seems to have been revoked, so #30 then triggers.

Hey all, I've implemented the delete timeout for revocation, although I've set the default at 20 minutes (increasing it from 3), so hopefully you never have to set it. :)

This should be fixed in the next release. Thanks!

PS: I've been doing some thinking about this as well around actually just dropping post-revocation OCSP checks completely. This used to work great around when I first wrote the provider, but more often than not now it just causes problems.

There is also much musing about the general unreliability of revocation infrastructure.

This will probably be what we do for 1.0.0, while we do some other housekeeping. At best it will be optional.
