utils: remove thread priority elevation
Remove UHD call to elevate thread priority to realtime from utils, and
add warning in documentation of set_thread_priority function. Setting
all threads to the same realtime priority can cause the threads to not
share access to the network interface fairly, which adversely affects
operation of the worker threads in UHD.
