cmd/geth, cmd/utils: geth attach with custom headers
This PR makes it possible to set custom headers. Example:
$ source setheaders && go run . attach -H "CF-Access-Client-Id: $CFID" -H "CF-Access-Client-Secret: $CFSEC" https://rpc.mainnet.ethpandaops.io
Welcome to the Geth JavaScript console!
instance: erigon/2022.09.1/linux-amd64/go1.18.5
Error handlng:
go run . attach -H "a bad header" https://rpc.mainnet.ethpandaops.io
Fatal: invalid http header directive: "a bad header"
Follow-up, this now also works with geth db <subcommand> --remotedb .
source ~/.headers && geth db get --remotedb https://geth.mainnet.ethpandaops.io -H "CF-Access-Client-Id: $CFID" -H "CF-Access-Client-Secret: $CFSEC" SnapshotRoot

the method debug_dbGet does not exist/is not available
It seems the debug module was not available

However, the flag is really wonky. I suspect this is a bug in urfave.
geth db get --remotedb -H "a: a" -H "b: b" -> two headers, a, and b
geth --remotedb -H "a: a" -H "b: b" db get -> one headerstring "[a: a, b: b]"
I'll investigate this a bit more
With the debug api enabled:
