[BUG] Turn on strictMode for propeller and propeller-manager config load

[pmahindrakar-oss]

Describe the bug

Currently though the configAccessor is defined to load the config in strictMode which makes sure incorrect config keys cause a fast failure , but it turned off during app initialization here

Similar behavior has been replicated in propeller manager too

• definition
• initialization

Expected behavior

StrictMode should be turned on to catch incorrect config errors faster
