Standardize ENV for query service

[shivanshuraj1333]

Right now, there's no standard way to configure environment variables for query service, for helm installation, the below ENVs are populated but similarly to running locally the ENVs are not well defined, it should match with the docker counter part.

from a container

         env:
         - name: CLICKHOUSE_HOST
           value: my-release-clickhouse
         - name: CLICKHOUSE_PORT
           value: "9000"
         - name: CLICKHOUSE_HTTP_PORT
           value: "8123"
         - name: CLICKHOUSE_CLUSTER
           value: cluster
         - name: CLICKHOUSE_USER
           value: admin
         - name: CLICKHOUSE_PASSWORD
           value: 27ff0399-0d3a-4bd8-919d-17c2181e6fb9
         - name: CLICKHOUSE_SECURE
           value: "false"
         - name: STORAGE
           value: clickhouse
         - name: ClickHouseUrl
           value: tcp://my-release-clickhouse:9000/?username=admin&password=27ff0399-0d3a-4bd8-919d-17c2181e6fb9
         - name: ALERTMANAGER_API_PREFIX
           value: http://my-release-signoz-alertmanager:9093/api/

but the same is missing for locally running the query service and the parameters are hardcoded in strings
eg
https://github.com/SigNoz/signoz/blob/develop/pkg/query-service/app/server.go#L113
https://github.com/SigNoz/signoz/blob/develop/pkg/query-service/app/clickhouseReader/reader.go#L146

@shivanshuraj1333 may i work on this

[shivanshuraj1333]

@Naresh-kumar-Thodupunoori
go ahead, it's an easy issue, just try to find all the env variables, and try to standardize them.

@shivanshuraj1333 Can you assign me this

[Naresh-kumar-Thodupunoori]

Hey @shivanshuraj1333 Should I have to standardize for every folder in query-service?

Hey @shivanshuraj1333 ,I did like to work on this issue. Wanted to confirm for Standardization do we want to use knoaf library ?

[shivanshuraj1333]

this one is relatively simple, just have all the ENV variables standardised at a place, right now they are scattered among files.
for loading the env variables we can keep what we use today. No need of knoaf at the moment
