RFR: JDK-8221713: JDWP spec - allow option is not described

[Alex Menkov]

Hi all,

Back in JDK10 "allow" option was implemented for dt_socket transport:
https://bugs.openjdk.java.net/browse/JDK-8061228
CCC: https://bugs.openjdk.java.net/browse/CCC-8061228
But this option was not reflected in "Connection and Invocation Details" 
page.
