Add ability to test feature branches in TeamCity

[SarahFrench]

Description

This PR

• allows TeamCity projects to test a feature branch in the downstream TPG and TPGB repos
• adds some comments and links to documentation to help people new to this approach of configuring TeamCity
• changes the default value of environment to "default", away from "public", as we have no concept of public TeamCity projects for the Google provider

These are the requirements that this PR fulfils:

• TPG
  • has one release branch
  • the release branch will be tested on Thursdays
  • the main branch will have nightly tests run all other days of the week (Mon-Wed, Fri-Sun)
• TPGB
  • has one release branch
  • the release branch will be tested on Fridays
  • the main branch will have nightly tests run all other days of the week (Mon-Thurs, Sat-Sun)

Changes in this PR

This PR makes the settings.kt file generated, and depending on whether version is ga or beta a different value is set for defaultDaysOfWeek, see here. These are the days that the main branch will be tested.

To determine which days the feature branch tests run, the testConfiguration class in this file is updated to check the environment context parameter and return either the default cron values (for main) or values specific to the feature branch.

How feature branch testing projects are set up in TeamCity

To set up a TeamCity project that tests feature branches one would need to:

• Manually create a new project, one per GA/Beta
• Manually create a VCS Root that points to the GA/Beta repo and the feature branch

• Set up context parameters environment and branch like in the screenshot below (note, other context parameters are needed to supply things like ENVs for configuring the provider during acceptance tests).
