Terraform Installer Versions Save

Add CPU Architecture check for aarch64 (on Linux)

• use regular arm binary as Terraform currently does not have a separate binary for arm64

Adjust movement of binary from download folder to destination

Add arm processor detection

Adjust latest_version algorithm to exclude alpha releases

fix latest version checking

• latest version fixes
  • no longer includes beta and rc versions
  • no longer requires sort --versions-sort argument in jq-based algorithm [issue #4]
• gather latest version only when necessary and after help [issue #4]
• added set -e error trap [issue #4]

Add checksum validation of downloaded file before installation

Correct fallback value for cpu architecture detection.

Adjust for use in CI/DevOps pipelines

Added -c option to leave binary in current directory (for CI/DevOps use)

Compatibility Release - works with either curl or wget and uses jq if installed

• checks for either curl or wget and uses whichever is present
  • defaults to curl if both installed
• if jq is installed - parses the latest version from hashicorp download page (instead of GitHub)
  • Avoids github api limit of 60 unauthenticated requests per hour
  • Useful if github release differs from version on hashicorp downloads
