Hardcoded JIRA issue regex is not compliant with atlassian documentation

[Martin Čambal]

We use prefixes for project keys with underscore e.g. D_ for development, I_ for infrastructure teams. Unfortunately the hardcoded regex for Jira issues doesn’t support underscore.

This is the existing regex [A-Z][A-Z0-9]*-\\d+, the requested change would be [A-Z][A-Z0-9_]*-\\d+

Based on the Atlassian documentation only formats that meet all of the following rules are supported:

• The first character must be a letter,
• All letters used in the project key must be from the Modern Roman Alphabet and upper case, and

• Only letters, numbers or the underscore character can be used.
  Examples:

  • Examples of supported keys: PRODUCT_2013, R2D2, MY_EXAMPLE_PROJECT.  
  • Examples of unsupported keys: 2013PROJECT(first character is not a letter), PRODUCT-2012(hyphens are not supported).
