Build and Test Windows MSI during release

[jsirianni]

Description of Changes

Implemented MSI building. The MSI package can be used to install, repair, and uninstall stanza.

Codebase Changes

• Added optional environment variables for log file path and database file path. This is because go-msi does not handle arguments very well when the path has spaces in it. Quoting should work but I get a strange wix error. Instead, I use environment variables to enable the log and database files.

Build Changes

• Added make targets for using vagrant to build an MSI package.
• Modified the release workflow to run on PR.
• Added condition to release workflow "release" and "build container" stages to ensure they only run on a tagged release.
• Added MSI building to release workflow, it will run on PR and pushed tag. The release stage will wait for the msi build, and then download the msi artifcats and bundle it with the Goreleaser release.

Please check that the PR fulfills these requirements

• Tests for the changes have been added (for bug fixes / features)
• Docs have been added / updated (for bug fixes / features)
• Add a changelog entry (for non-trivial bug fixes / features)
• CI passes
