This applies a full rename across the repository to reflect that the
term "blacklist" is controversial in the tech community and that using
the term "disallowed-list" is more explicit in it's purpose.

This applies a full rename across the repository to reflect that the
term "whitelist" is controversial in the tech community and that using
the term "allowed-list" is more explicit in it's purpose.

This is to make this rule consistent in naming with the other list based
rule names (*-allowed-list and *-disallowed-list).

Previously *-whitelist, *-blacklist and *-requirelist rules were renamed
to a consistent naming pattern of *-allowed-list, *-disallowed-list and
*-required-list respectively. This commit adds aliases so that the old
rules can continue to operate; this allows backwards compatibility to be
maintained.

A consequence of this is that violations for the previously named rules
will show up with the new name. A developer may also get some confusing
results if they happen to have the same rule defined with both names and
different options.

This replaces the declaration-property-unit-disallowed-list rule with
the shorter unit-disallowed-unit one to create a simpler example image.
