chore: Determine the installer version based on Git revision and tags

[evanspearman-a]

What was the problem/requirement? (What/Why)

DCC Submitter installers get their version from an environment variable, or use "00000000" for dev builds, then add the current date on the end. Instead, installers should have versions based on repository tags. If the latest tag matches the current commit hash, the version should just be the latest tag. Otherwise, the version should be the latest tag plus the short commit hash of the current commit.

What was the solution? (How)

Change the way the installer building script determines the version to match what was described above. Additionally I added a flag for overriding the version.

What is the impact of this change?

Versions will be related to the tags.

How was this change tested?

I build the installer, ran it, and verified that installer_version.txt contained the correct version.

Please run the integration tests and paste the results below

N/A

If installer/ was modified or a file was added/removed from src/, then update the installer tests and post the test results below
