Describe the feature you'd like
Currently there is SocketPath newtype defined in cardano-api/src/Cardano/Api/TxSubmit/Types.hs but it has two problems:

• It is exported from that module but that module is private to cardano-api.
• The name is a little too general. NodeSocket would be better.

[erikd]

Since we want to rename and export this, it might be a good idea to remove duplicate defintions (this is from the 1.35.3 tag):

> pwd
/home/erikd/Git/IOHK/NewCodeBase/cardano-node
> grep -r ^newtype --include=\*.{hs,lhs} . | grep -v dist-newstyle | grep SocketPath
./cardano-api/src/Cardano/Api/TxSubmit/Types.hs:newtype SocketPath = SocketPath
./cardano-api/src/Cardano/Api/LedgerState.hs:newtype SocketPath = SocketPath
./cardano-submit-api/src/Cardano/TxSubmit/CLI/Types.hs:newtype SocketPath = SocketPath
./cardano-node/src/Cardano/Node/Configuration/NodeAddress.hs:newtype SocketPath = SocketPath
./cardano-cli/src/Cardano/CLI/Types.hs:newtype SocketPath = SocketPath { unSocketPath :: FilePath }

Maybe this even belongs in something like cardano-base.

Also it must have an accessor function as well. Eg:

newtype NodeSocket = NodeSocket { unNodeSocket :: FilePath }
