DefaultEndpointResolver throws compile warnings

[jbelkins]

Describe the bug

Every AWS service's default endpoint resolver throws this warning three times when compiled:

No calls to throwing functions occur within 'try' expression

This is apparently due to the CRT functions being called no longer throwing.

To fix, remove try from method calls to methods that cannot throw.

Expected Behavior

Compile main branch of SDK. Default endpoint resolvers should compile without warnings.

Current Behavior

Compile main branch of SDK. Default endpoint resolvers compile with the warning

No calls to throwing functions occur within 'try' expression

thrown three times.

Reproduction Steps

N/A

Possible Solution

Remove try from method calls to methods that cannot throw.
