ODBC 8.1 driver with `localhost` causes long delays

Dolt can experience very long latency with oracle ODBC driver 8.1 and a `localhost` connection. This seems to be the result of the driver attempting to talk to the IPv6 localhost address `::1`. The symptom is multiple `SYN / [RST, ACK]` responses over the wire:


Together these failed IPv6 packet attempts take several full seconds to get past.

There are two workarounds possible:

1. Use `127.0.0.1` instead of localhost in the connection string, which forces IPv4

In your connection string, change this:

`DRIVER={MySQL ODBC 8.1 ANSI Driver};SERVER=localhost;OPTION=3;PORT=3306;DATABASE=mydb;USER=root;PWD=;PERSIST SECURITY INFO=True;`

To this:

`DRIVER={MySQL ODBC 8.1 ANSI Driver};SERVER=127.0.0.1;OPTION=3;PORT=3306;DATABASE=mydb;USER=root;PWD=;PERSIST SECURITY INFO=True;`

2. Use ODBC driver version 8.0, listed here as 8.0.32:

It's possible to install both 8.0 and 8.1 side by side. Specify which version to use in your connection string as above.

Either workaround will restore latency to normal levels.
