ASGARD-1202 Check ELB instance health during auto assessment
The M3 instance types do not need to be added through custom configuration anymore. They haven't for a long time.
Stop parsing HTML for hardware profiles. Hard-code the updated metadata.
Fixed typo
Removed support for reserved instance pricing and spot pricing.

We don't need it. It's not very accurate. It's costly and risky to try to support it. The data is better gotten elsewhere.
Added links to better sources of data the user can look at.
Remove deprecated launchConfig/cleanup that is no longer referenced by our Jenkins jobs
Removed JsonpStripper now that spot.js is no longer a concern and we don't have other jsonp to strip.
No need to try or catch anymore. There's no remote call, so no chance of surprise failure.
Parse m3 instance type prices
Update source of pricing data and offline copy
Add table footer for easier detection of page scroll end
Upgrade to aws-java-sdk-1.6.6 and transitive dependencies.

Update RestClientService to use non-deprecated retry handler.
Update assumptions about instance types based on new enum values.
Alter strategy for brieg error email text, based on AWS's new toString() algorithms.
