After the following commits, GUI should be updated:

1) https://git.opendaylight.org/gerrit/#/c/49687/
Removing deprecated SF fields - The SF fields nsh-aware and request-reclassification were deprecated in Beryllium. The fields were added to the SF-type, so use those instead.

In GUI (http://localhost:8181/index.html#/sfc/servicefunction) we can still see a field "NSH aware", but it's empty. This field should be removed, as nsh-aware is no longer an attribute of a Service Function, or at least updated with the nsh-aware field of the SF type this SF belongs to.

2) https://git.opendaylight.org/gerrit/#/c/49546/
Deprecating the SFC and RSP symmetric flags - Chain symmetry is now a function of the SF-type bidirectionality flag - The SFP symmetry flag, if present, will override the SF-type bidirectionality flag

In GUI (http://localhost:8181/index.html#/sfc/servicepath) there is a check box for "Symmetric path" which doesn't show the resulting symmetric feature of the path. That is, in case the SF type of one SF in the chain is bidirectional and the symmetric field in SFP is not set, this check box appears unchecked, which is confusing, because the path is actually symmetric.
An easy solution could be renaming this check box for example as "Force symmetric path", to reflect just the meaning of the symmetric field in SFP, not the resulting symmetric feature of the path.
