Add links to Daily shifter summaries in Shiftleader report

[nothingface0]

In day-by-day notes, add links instead of the placeholders:

They could be either:

1. Links towards CMSonline Elogs:

   This will be counterintuitive for the Shifter who will have to create the summary, create the Elog on CMSonline, then go back to Certhelper to add the Elog link to the summary.
   Reminder that there's currently no way to interface with CMSonline.

2. Links towards CertHelper which generate the summary on demand.

   This is both aasier to implement and there will be no extra steps for the Shifters.
