This is to suppress ASAN false positives for static variables.
For example, the ServiceMethodTable::m_slots is sometimes reported as leaked.

ASAN report example:

Direct leak of 32 byte(s) in 1 object(s) allocated from:
    #0 0x7feb0d3f4647 in operator new(unsigned long) ../../../../src/libsanitizer/asan/asan_new_delete.cpp:99
    #1 0x55b3be15e430 in declare_static<syncd::ServiceMethodTable::SlotBase, syncd::ServiceMethodTable::Slot, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9> syncd/ServiceMethodTable.cpp:74
    #2 0x55b3be15e430 in declare_static<syncd::ServiceMethodTable::SlotBase, syncd::ServiceMethodTable::Slot, 10> syncd/ServiceMethodTable.cpp:81
    #3 0x55b3be15e430 in __static_initialization_and_destruction_0 syncd/ServiceMethodTable.cpp:85
    #4 0x55b3be15e430 in _GLOBAL__sub_I_ServiceMethodTable.cpp syncd/ServiceMethodTable.cpp:121

this sounds really bad, you are implementing missing import here, why this way ?

It is rather a callback than a missing import. This is one of the ways to configure ASAN/LSAN.
Another way is to have a file (e.g. supressions.txt) and pass a path to it via env variable options.
The 'callback' approach is simpler and allows to keep all the asan-related things in asan.cpp.
This also seems to be a more popular way to configure the suppressions (e.g. chromium does this).
