Implement DNS-over-TLS client

[DGDG14]

Please add the secure DNS OR CUSTOM DNS option to get privacy.
For example
Once traffic is processed from pcapdroid than it will directly go to router and then it will go to the service provider DNS and then it will go to the destination this currently happening.
And I'm thinking of this once traffic is process by pcapdroid at the end of VPN tunnel add option for where traffic needs to be sent user can select to add custom DNS or a secure DNS.
for secure DNS there are many free secure DNS for example adguard DNS or CLOUDFLARENET DNS and many more which you can also provide as list of DNS
I know this is kind complicated request.
This could help alot VISIBILITY WITH PRIVACY.

Implementing a dns over tls client could provide additional info about the connections made to a certain domians particularly which are made through quic protocol which won't give out the sni too.
Also in decryption mode , it could be useful to keep outgoing requests secure.
Though priority of this request could be evaluated by the dev.

For providing secure dns queries in tls decryption mode , the reverse-dns mode of mitmproxy can be used and specify upstream dns server.

--mode reverse:dns://8.8.8.8

Replace google dns with cloudflare dns

PCAPdroid can now be used in conjunction with InviZible Pro, to encrypt the DNS traffic with DNSCrypt/DNS-over-HTTPS
see https://emanuele-f.github.io/PCAPdroid/advanced_features#42-doh-support for more details.
Integrating dnscrypt-proxy directly could be possible in the future but it's involved, both because it will probably require relying on pre-built executables and because the UI for the DNSCrypt settings needs to be implemetend in PCAPdroid
