Convert CLI to urfave v2

Browse Source 
Followed the Migration Guide at https://cli.urfave.org/migrate-v1-to-v2/
The major changes not pointed out in the migration guide are:
- context.Args() no longer produces a []slice, so context.Args().Slice()
  in substitued
- All cli.Global***** are deprecated (the migration guide is somewhat
  unclear on this)

[![codecov](https://codecov.io/gh/urfave/cli/branch/v1-maint/graph/badge.svg)](https://codecov.io/gh/urfave/cli)
cli is a simple, fast, and fun package for building command line apps in Go. The
goal is to enable developers to write fast and distributable command line
applications in an expressive way.
## Usage Documentation
Usage documentation for `v1` is available [at the docs
site](https://cli.urfave.org/v1/getting-started/) or in-tree at
[./docs/v1/manual.md](./docs/v1/manual.md)
## Installation
Make sure you have a working Go environment. Go version 1.18+ is supported.
### Supported platforms
cli is tested against multiple versions of Go on Linux, and against the latest released
version of Go on OS X and Windows. For full details, see
[./.github/workflows/cli.yml](./.github/workflows/cli.yml).
### Build tags
You can use the following build tags:
#### `urfave_cli_no_docs`
When set, this removes `ToMarkdown` and `ToMan` methods, so your application
won't be able to call those. This reduces the resulting binary size by about
300-400 KB (measured using Go 1.18.1 on Linux/amd64), due to less dependencies.
### Using `v1` releases
```
$ go get github.com/urfave/cli
```
```go
...
import (
"github.com/urfave/cli"
)
...
```
