Rename 'include/mesos/slave' to 'include/mesos/agent'

[Zhou Z Xing <xi...@cn.ibm.com>]

Dear developers and users,

While doing ticket MESOS-5230, we found that it is necessary to rename
folder 'include/mesos/slave' to 'include/mesos/agent'. With the change of
this folder, it may affect that:

   1. with command "make install", the header files installation location
   will be changed to '$(DESTDIR)/include/mesos/agent'.
   2. all the files that include the headers in this folder need to change
   their include claim
   3. for the protos that use 'mesos.slave' package need to change to use '
   mesos.agent' package

As a result, if this change affects your program or environment, please let
us know. We are planning this change soon, welcome your comments on this!

Thanks & Best Wishes,
