CLI address parsing is overly restrictive

This should work:

host=pingguo.local:read-resource
The node name is not a valid identifier 'pingguo.local' or the format is wrong for prefix 'null'

The validation in Util.isValidIdentifier() is limiting things to Character.isJavaIdentifierPart(c[i]) || c[i] == '-'

The org.jboss.as.controller.PathElement class is what validates address elements as we create them from dmr nodes. It uses the following patterns to validate:

/**

• A valid key contains alphanumerics and underscores, cannot start with a number, and cannot start or end with
• {@code -}

  .
  */
  private static final Pattern VALID_KEY_PATTERN = Pattern.compile("[_a-zA-Z](?:[-_a-zA-Z0-9]*[_a-zA-Z0-9])?");

private static final Pattern VALID_VALUE_PATTERN = Pattern.compile("\\*|[^*
p

p

]+");

Since '=', ':', ',' and '(' have special significance in the CLI there will need to be a mechanism to quote or escape those if used in path element values.
