Update docs on the use of wildcards in destination names

In the security guide, https://access.redhat.com/site/documentation/en-US/Fuse_MQ_Enterprise/7.1/pdf/Security_Guide/Fuse_MQ_Enterprise-7.1-Security_Guide-en-US.pdf pg 88/89 describes how to configure the authorization plugin.

There is a paragraph on wildcards, but we have had some customers tripped up - in that it doesn't mention that destination names are tokenized on the '.' character.

So you might expect that a filter of TEST> would apply to all destinations beginning with TEST but this doesn't work:

<authorizationEntry queue="TEST>"
read="admins"
write="admins"
admin="admins" />

We should clarify, the filter needs to be '.' delimited e.g USERS.TEST>
