adding login params for autologin

[atarkowska]

This PR should allow passing login parameters to auto login into Insight.

JNLP file now gets host port and session ID that is minimum to log in

<property name="jnlp.omero.host" value="trout...org"/>
<property name="jnlp.omero.port" value="4064"/>
<property name="jnlp.omero.sessionid" value="79e4596a-bb8c-470f-8e6a-47b91ed0c5ab"/>
<property name="jnlp.omero.web.host" value="http://omero.testdomain.com:4080/"/>

Note: Webstat page is also available when user is not logged in. In this case there will be default server host and port set and no sessionid provided. These parameters should be used as a helper to choose the right server from the list.

In general, big 👍 for this @aleksandra-tarkowska. The only caveat that might arise is the need for a static webstart page so that we can sign it: https://trello.com/c/4KjZpcX2/494-sign-webstart-jnlp-file

@joshmoore There is nothing stopping anyone from replacing template by bin/omero config set omero.web.webstart_template as long as we have signed file and test it. First lets see if params works and Insight will be able to use them.

Makes sense! (Think the hope, though, is that we can provide a signed one, which is going to be tricky)

[dominikl]

SessionID is now included in the jnlp properties. Good to merge.

[joshmoore]

Can I propose we leave open until we have the two working together in case there is some back and forth?

Assuming that all testing for this PR was commented under #3820, merging.
