        10 character string with characters(A-Z). Assumes that issue number is no larger than 999,999. e.g. not more
        than a million issues.
        This pads the issue key to allow for proper string sorting so that the project key is always 10 characters and the
        issue number is always 6 digits. e.g. it appends the project key '.' until it is 10 characters long and prepends 0
        so that the issue number is 6 digits long. e.g. CONF-102 == CONF......000102. This is to allow proper string sorting.
