Xapp-frame-py get_constants() function calls c-code RMR library's
rmr_get_consts() function what allocates dynamic memory with strdup
call and returns allocated string to the caller in this case to
python's get_constants() via ctypes interface. This memory should be
freed, otherwise it causes memory leak. With this commit update RMR
version to 4.8.0 what has rmr_free_consts() function and call this
function in the end of get_constants() function to release allocated
memory.
Note that from now on it is required to have RMR version 4.8.0 or
newer version installed because rmr_free_consts() function was
introduced first time in RMR version 4.8.0. That's why bump
xapp-frame-py major version, new version is 3.0.0.
Temporally out scoped few unit test files because some change in
RMR version 4.5.2 causes UT failure. UTs will be fixed later.
