Update neo4j driver - new driver is pure Golang

[davisford]

Is your feature request related to a problem? Please describe.
Current driver in golang is v1.7.4

Newest driver from neo4j is v1.8.3

As of version 1.8.0 the driver was re-written entirely in Go, whereas the older drivers were a Go wrapper around their seabolt C driver. This would bring the driver up to the latest including support for new protocols that are implemented in Neo4j 4.x, add bugfixes, improvements, as well as the ability to drop the C binary and Go wrapper.

Describe the solution you'd like
PR that updates golang driver to latest with go mod tidy and tests still passing.

Describe alternatives you've considered
None

Additional context
One of the issues we're seeing with migrate + neo4j is failure in concurrent situations. We deploy our containers in Kubernetes with an init container that runs the migrations. Unfortunately, the current neo4j migrate implementation does not support concurrency, and if you run two identical migrations concurrently it fails miserably.

I'm hopeful that with the newer driver, this will be improved as the bolt protocol itself has graduated to new versions with better support.

If you'll accept a PR for this, and we can get it pushed through quickly let me know and I'll be happy to try to provide one.

We're using v1.8.1 which is written in pure Go. Feel free to update to v1.8.3
