Add node message support for ACLK new architecture

[stelfrag]

Summary

Add initial support for node info message

Component Name

aclk, database

Test Plan

The code is not active yet (it is tested with the new architecture in a separate branch)

[underhood]

an additional small nit picky comment would be should those files and functions be called sqlite? I know they are called out of your event loop but same time this particular part seems it has nothing to do with database

Sorry, noticed some build failures on ubuntu 16.04, will have a quick look...

I see that -- I will take a look as well

I think if fails because ACLK_NG cannot be built there (lack of protobuf is mentioned in configure), so the compile goes on to build with Legacy. Maybe the #ifdef should be for ACLK_NG ? Cause aclk/aclk_charts_api.c is not built when not in ACLK_NG ?

But I also get some (which when handled, proceeds to build ACLK_NG, and the binary links):

aclk/aclk.c: In function ‘ng_aclk_host_state_update’:
aclk/aclk.c:972:47: error: ‘UUID_STR_LEN’ undeclared (first use in this function)
     query->data.node_update.node_id = mallocz(UUID_STR_LEN);

Checking ACLK_NG works

Also works as - is when you pass --disable-cloud explicitly

I think the latest protobuf from their repositories in 16.04 seems to be 2.6.1. In configure we want >3, so checking for PROTOBUF fails, but actually we detect having /usr/bin/protoc. So if you request --use-system-protobuf there, it won't fail, but won't build ACLK_NG either. Maybe we should check for protoc --version > 3 ... ? (Not related to this PR).

Added ACLK_NG check for now
