Confirm that cmdi file is returned when the HTTP-accept header has “application/x-cmdi+xml”

[milanmajchrak]

TODO:

• we need to have some Item with CMDI file - maybe it could be added into python import script?

7. Persistent Identifiers - Centres need to associate PIDs (handles or DOIs) with their metadata records.

• it redirects to a CMDI file for the HTTP-accept header “application/x-cmdi+xml”
• it redirects to an HTML file when accessing it from a browser
  Individual files (e.g. a text, zip or sound file) can be referred to with either the handle of
  the describing metadata record in combination with a part identifier11 or with another
  handle.

Works on port 88 with good nginx
curl -k http://dev-5.pc:88/handle/11234/1-5438 -L -H "Accept: application/x-cmdi+xml"

does not work on bad nginx
curl -k https://dev-5.pc:8443/handle/11234/1-5438 -L -H "Accept: application/x-cmdi+xml"

It is because of nginx directive

if ($query_string ~* "format=cmdi"){
                rewrite ^/(.*)handle/(.*)$ http://$http_host/server/cmdi/oai-metadata?metadataPrefix=cmdi&handle=$2? redirect;
            }
            if ($http_accept ~ "(.*cmdi.xml*)"){
                rewrite ^/(.*)handle/(.*)$ http://$http_host/server/cmdi/oai-metadata?metadataPrefix=cmdi&handle=$2? redirect;
            }

which IS in wiki. (and enables other header values, since regex is used, and other kind of links as well
curl -k http://dev-5.pc:88/handle/11234/1-5438?format=cmdi -L
)

Some Item could have specific CMDI file - during creation the admin upload a cmdi file which will be returned. He need to click on Has CMDI checkbox. Confirm that specific cmdi file is returned.

• Return uploaded CMDI file from the CMDI bundle if:

1. The Item has metadata local.hasCMDI = yes
2. The Item has file in the CMDI bundle

• Create a test for that

waiting for tests and then review
