Failure to start in VIC appliance

[andrewtchin]

In CI, @mdharamadas1 deployed and initialized a 1.3.1 VIC appliance. When navigating to the Admiral interface a blank page appeared at the SSO redirect.
Logging into the appliance showed that the Admiral process was running, but the Admiral journal showed

Feb 12 16:28:09 wdc-harbor-ci.eng.vmware.com start_admiral.sh[1639]: Exception in thread "pool-1-thread-1" com.vmware.admiral.auth.idm.psc.saml.sso.admin.SsoAdminClientException: Can not create SSO AdminClient.

A reboot of the appliance seems to have resolved this error, but it is initially in an unusable state.

At a minimum, the Admiral process should exit if it is unable to display an error message in case of failure https://github.com/vmware/vic-product/blob/master/installer/docs/DESIGN.md#requirements

How should users troubleshoot this? Please add these steps as part of #249

Log bundle is attached, please let me know if there is additional information that should be gathered in the log bundle

@andrewtchin Is this issue still reproducible?

@martin-borisov We haven't seen it in a while, though I would like the error documentation and troubleshooting steps to still be addressed. Would you like me to copy those into the relevant issues?
