[cfgmgr]: Integrate MACsecMGR with sonic-buildimage (#1627)

1. Fix bug about the return value of `get_value`, it should return `true` if it's OK
2. Fix bug about the type of `MACsecProfile::priority`, the original `uint8_t` will cause a `lexical_convert` failure when the priority is a integer.
3. Polish log in `get_value`.
4. Change the predefined paths for sonic-buildimage integration
