[hostcfgd] Fix Boolean String Evaluation (#5248)

Browse Source 
New attribute 'has_timer' introduced to init_cfg.json does not evaluate
as Bool, rather it evaluates as string. This PR fixes this issue. Also,
this PR fixes an issue when there is system config unit (snmp, telemetry) that
has no installation config (WantedBy=, RequiredBy=, Also=, Alias=) settings
in the [Install] section. In the latter case, the .service should not be enabled.
