Computer Name Regex Validation

[timothyd09]

Is your feature request related to a problem? Please describe.
For HST, we have a very standard naming convention for our devices that can follow a regex pattern. It would be nice to have the option to use a regex pattern for the naming convention model rather than the current rule set.

Describe the solution you'd like
In the AppSettings.json and AppSettingsPE.json files, please add new options called "ruleRegexPattern" and "ruleRegexPatternEnabled". In the front end, have this rule be evaluated to look at the computer name field to determine if the value meets the regex expression. If it does, allow the next button to be available.

Describe alternatives you've considered
We can use the existing rules for now, but they are limited in their functions.
