[STORM-2757] Fix broken log links when HTTPS is in use

[Ethanlm]

jira: https://issues.apache.org/jira/browse/STORM-2757

We have HTTPS configs for UI and Logviewer. But it's not working properly.

We should expect:

UI	LogViewer	scheme of log links	port of log links
HTTP	HTTP	http	logviewer.port
HTTP	HTTPS	https	logviewer.https.port
HTTPS	HTTPS	https	logviewer.https.port
HTTPS	HTTP	should not work	should not work

Tested it manually with all four combinations by visiting pages/links.

UI	LogViewer	all UI pages	Nimbus log	Supervisor log	Worker log	Event Log	dumps and download	logviewer search	deap search
HTTP	HTTP	✓	✓	✓	✓	✓	✓	✓	✓
HTTP	HTTPS	✓	✓	✓	✓	✓	✓	✓	✓
HTTPS	HTTPS	✓	✓	✓	✓	✓	✓	✓	✓
HTTPS	HTTP	✓	x	x	x	x	x	x	x

✓ means working properly. x means not working.

These are expected behaviors.
