Increase timeout for deleting networks

[danawillow]

Our tests have been timing out a lot on network deletion lately. I'm not quite sure why it takes more than 4 minutes to delete a network but let's give it 10 minutes just in case.

Checked by running firewall tests, which are currently failing in CI:

=== RUN   TestAccComputeFirewall_importBasic
=== RUN   TestAccComputeFirewall_basic
=== RUN   TestAccComputeFirewall_update
=== RUN   TestAccComputeFirewall_priority
=== RUN   TestAccComputeFirewall_noSource
=== RUN   TestAccComputeFirewall_denied
=== RUN   TestAccComputeFirewall_egress
--- PASS: TestAccComputeFirewall_noSource (296.32s)
--- PASS: TestAccComputeFirewall_basic (306.30s)
--- PASS: TestAccComputeFirewall_importBasic (316.45s)
--- PASS: TestAccComputeFirewall_egress (295.70s)
--- PASS: TestAccComputeFirewall_denied (295.37s)
--- PASS: TestAccComputeFirewall_priority (305.40s)
--- PASS: TestAccComputeFirewall_update (307.44s)
PASS

I'm minorly concerned about the 10 minute wait period, which isn't a great user experience, but... on the other hand, I don't see a better alternative, and this is definitely better than leaving it broken.
