[CalvinWilkinson]

Complete The Item Below

• I have updated the title without removing the 🚧 emoji.

Description

Add some options to the getVariables() function in the RepoClient and OrgClient class. These options will be used to signify how to trim the variable values.

Add the following options:

1. Add the ability to trim spaces, \n, and \r characters from the beginning and end of the variable values.
2. Add the ability to return all of the values in uppercase or lowercase

Each option should represent a different trimming behavior.

Here are the trimming behaviors:

/**
 * Represents different carriage return and/or line feed trimming types.
 */
export type TrimType = 
    "TrimStart" |
    "TrimEnd" |
    "TrimBoth" |
    "None";

Unit Tests

Reasons for local unit test execution:

• Unit tests might pass locally but not in the CI environment during the status check process or vice-versa.
• Tests might pass on the developer's machine but not necessarily on the code reviewer's machine.
• If you notice that the test status check has passed but the test failed locally, please notify a project maintainer!

💡Warning💡
If the unit tests pass remotely and are not executed locally, this means we could be letting a bug slip into production.
Though bugs will always exist in some capacity, we should all do our part to help prevent them from happening.
