terraform: add HMAC secret key

Add a secret key to be used for computing HMACs of IP addresses
for vuln DB requests.

We use an HMAC (encrypted hash) rather than a hash alone to obfuscate
IP addresses so that no one can check a guessed IP against a hash
without knowing the secret.

Since no one ever needs to decode the result, the secret was generated
once, stored in Google Cloud Secret Manager, then discarded. It is
not stored anywhere else.
