Limit sessions while runnning with evaluation license

[codescape]

While running with an evaluation license the session count should be limited to 100 sessions. A message should inform about this limit in the configuration and a message should appear when trying to start session 101.

This allows to run and evaluate Scrum Poker while at the same time adding a good reason to purchase a license as today several „customers“ run Scrum Poker with evaluation licenses over many months.

Snippets

if (license.isEvaluation()) {
    /* check number of total and running sessions */
}

Tasks

• check for evaluation license and number of total sessions on new session start
• extract license management into separate service?
