Select ssh host

If the environment variable OOD_SSH_HOSTS is set then a dropdown button will appear in place of the regular single click button. OOD_SSH_HOSTS completely overrides OOD_SHELL. OOD_SSH_HOSTS is expected to be a comma delimited list of colon delimited pairs. The first half of the pair needs to be the SSH host and the second should be a human-friendly label for the cluster. The URL to the Shell app may be customized by setting OOD_SHELL_URL (e.g. OOD_SHELL_URL=/pun/sys/alternative-shell-app/ssh).

For example at OSC we would use OOD_SSH_HOSTS=owens.osc.edu:Owens,ruby.osc.edu:Ruby,pitzer.osc.edu:Pitzer.

Note that there is no support at this time for filtering clusters, which is not ideal in cases where not all users have access to a given cluster.

Other decisions of note:

• The rendering engine has been partially changed to Handlebars instead of Rendy to support conditionals and loops
• Bootstrap CSS and JS have been included in the project files, and were previously served via a CDN

I think the design should change so OOD_SSH_HOSTS changes from:

/pun/sys/shell/ssh/owens.osc.edu:Owens,/pun/sys/shell/ssh/ruby.osc.edu:Ruby,/pun/sys/shell/ssh/pitzer.osc.edu:Pitzer

to

owens.osc.edu:Owens,ruby.osc.edu:Ruby,pitzer.osc.edu:Pitzer
