cubicweb #2709044 Enable override of tab label with string or string with an RQL execution [in-progress]

Right now tab labels can be defined in the following way :

  • tabid
  • use a tuple with tabid tabkwargs - where tabkwargs can contain key "label" with a string

It would be nice to enable a way of defining a "dynamic tab label". Two input arguments would be given

"custom label %s", "Any X WHERE ... "
