Previously, using the command omd config set APACHE_TCP_ADDR with a IPv6 address would fail. For example, the command

$ omd config set APACHE_TCP_ADDR "[::]"

resulted in Invalid value for '[::]'. Does not match allowed pattern.

With this Werk, it omd only checks that a Listen directive for Apache can be constructed from the APACHE_TCP_ADDR. In particular, this a IPv6 address can be configured. Such an address must be surrounded by square brackets.
