Site ICON lookup causing a DNS flood of requests to DNS server

[RonV42]

Steps To Reproduce

1. In Docker stop and restart container
2. Open the Windows Desktop client
3. As you scroll down the icons for the sites will start to fill
4. My DNS server reports:
   RATE_LIMIT | Client 192.168.30.221 has been rate-limited (current config allows up to 1000 queries in 60 seconds)
5. After the site icons stop filling and have a generic placeholder

Expected Result

I would expect that the ICON files should be cached locally not looked up when the Bitwarden container is started, and a client connects.

Actual Result

I would expect the ICONs to cache and be presented to the client vs a large block of DNS lookups to go to the site and pull the ICONs. There could be a Time to Live to refresh ICON's to keep them up to date.

Issue Tracking Info

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.
