(POOLER-150) Synchronize checkout operations for API

Browse source 
This commit adds a shared mutex to vmpooler API so that checkout requests can be synchronized across threads. Without this change it is possible in some scenarios for vmpooler to allocate the same SUT to different API requests for a VM.
