Describe the bug
BytePS needs to create socket hard-coded at this path:

byteps/byteps/common/communicator.h

Lines 34 to 35 in b9811f7

#define BASE_SOCKET_PATH_RECV "/usr/local/socket_recv_"
#define BASE_SOCKET_PATH_SEND "/usr/local/socket_send_"

As a result, BytePS cannot be used without root permission. Running BytePS without root permission gives:

[2019-06-27 11:01:05.326916: F byteps/common/communicator.cc:135] Check failed: (ret) >= (0) /usr/local/socket_send_0 bind failed: Permission denied

We will make these paths configurable. Also, maybe use /tmp/ as default path, though /tmp/ is a dangerous location for other reasons..

@ppwwyyxx Commit 5dabf0c should fix this. The default path is changed to /tmp. You can also configure the path by setting BYTEPS_SOCKET_PATH to like /your/path.
Let me know if it works for you.
