Add support for name_prefix to google_compute_ssl_certificate

[cblecker]

Fixes #10546.

Haven't made docs yet, but wanted to get code up for review. Adds name_prefix option, reusing code from https://github.com/hashicorp/terraform/blob/master/builtin/providers/google/resource_compute_instance_template.go.

Thanks for jumping on this @cblecker! This looks great. I love that name and name_prefix are both optional now; the only things that it would be cool to add is just a quick test case that exercises a code path where the config specifies neither name nor name_prefix, and a documentation update specifying the new attribute and reflecting that both are now optional.
