[Feature] Native Golang Git implementation

[tristanmorgan]

Description

Consul-Terraform-Sync has a dependency on Terraform, that depends on a library called Go-getter and that depends on git (and hg) as an os executable. This means when running even the CTS intro it will fail if git is not installed locally.

Use Cases

The static binary is capable of executing within a from-scratch docker container but fails if a git hosted terraform module is referenced.

Alternative Solutions

if the dependant library go-getter was updated to use golang native code for git it would benefit multiple downstream products.

Additional context

There is already an issue raised for Use a Pure Go Library for GitGetter requesting this in Go-getter

Also the HCP Terraform Agent has a native implementation
