Add devcontainer configuration

[dracco1993]

Description

Add configuration for docker vscode devconatienr

BONUS:

• Add .dockerignore to decrease synced file traffic and improve performance when using docker
• Add .gitattributes to tell git to use the correct linefeeds, regardless of platform
• Add .github/PULL_REQUEST_TEMPLATE.md to maintain a reasonable standard for PRs
  • This was shamelessly pulled from another project I help work on, The Blue Alliance (template)
  • It doesn't have anything to do with the rest of this PR, so I can pull it out if desired; I really just included it as a potential starting point

Motivation and Context

It helps makes development more straight forward for new contributors.

Thank you for this, but right now we are focused on getting to MVP (minimum viable product) so it can go into the hands of teams for testing.

Until we have that, things are changing so fast that we won't be pulling in PRs for other features. I am keeping this open so that we can look at it after we have an MVP out to teams.
