Run tests in serial and update multi-peer test (#269)

Updates test workflows with serial execution to avoid collision 
of ports and resource names.

Also, used -exec sudo flag for UNIX tests and removed not-needed
 limits configuration on Linux and added a 5 minutes timeout.

Updated the multi-peer tests in the client/internal/engine_test.go
 to provide proper validation when creating or starting 
a peer engine instance fails.

As some operations of the tests running on windows
 are slow, we will experiment with disabling the Defender before 
restoring cache and checkout a repository, then we reenable 
it to run the tests.

disabled extra logs for windows interface
