Change Chia Root CA to expire 31 Dec 2037

[emlowe]

Technically, this generates a new Root CA that uses the same key material and serial number, such that all old certificates and new certificates remain valid in both directions. That is, old certificates generated from the old CA will validate with the new CA, and new certificates generated from the new CA will validate with the old CA.

This extends the expiration out to 31 Dec 2037

The procedure is as follows:
Generate new signing request : openssl x509 -x509toreq -in chia_ca.crt -signkey chia_ca.key -out newca.crs
Generate new CA with same serial: openssl x509 -req -days 4425 -in newca.csr -signkey chia_ca.key -out chia_ca.crt -extfile ./renewedselfsignedca.conf -extensions v3_ca -set_serial 0x5C8A71239328650EB9FEF85CEC32BF779CA6A0C5

also included the configuration file used to set the extensions for future use.

The chia_ca_old.crt can probably be deleted after verification that this works. I have tested it locally and my node can connect without issue to the network

Just tested this as well on a fresh install/chia root and expiration date shows up properly, and I was able to get peers and starting syncing fine. Did you want to delete the old ca before we merge this, or later?

@emlowe and @cmmarslender have spoken outside this PR to address the open question in this thread - merging.
