Removing white spaces from provided values

[cniackz]

To fix: #2755

Explanation:

All I am doing is to trim the spaces introduced by the user so that we avoid an invalid configuration:

API: SYSTEM()
Time: 14:05:47 UTC 06/30/2023
DeploymentID: ad79aacc-3ffb-4726-9ff3-6cc7ca58b27a
Error: Invalid site configuration: region ' us-west-rack-2' is invalid, expected simple characters such as [us-east-1, myregion...] (*fmt.wrapError)
       7: internal/logger/logger.go:258:logger.LogIf()
       6: cmd/config-current.go:493:cmd.lookupConfigs()
       5: cmd/config.go:218:cmd.initConfig()
       4: cmd/config.go:189:cmd.(*ConfigSys).Init()
       3: cmd/server-main.go:452:cmd.initConfigSubsystem()
       2: cmd/server-main.go:423:cmd.initServerConfig()
       1: cmd/server-main.go:662:cmd.serverMain()

I think this can be generic as in non of our configurations we need leading or trailing spaces to work, so trim seems to be the solution here.
