Removes a log message that corrupts support_archive zip package

[aorcholski]

JIRA

Description

At startup, the operator immediately issues a log line :

{"level":"info","ts":"2025-01-27T14:02:26.877Z","logger":"install-config","msg":"envvar content read and set","envvar":"modules.json","value":"..."} 
PK^C^D^T...

which precedes the first ZIP header so the package can't be unpacked by some implementations of zip command.

Changes:

• removed global initialization of the Modules from v1beta1(2)/convert_from packages to fix support_archive command
• GetModules function is called by all operator subcommands to put the message at the beginning of a log file

How can this be tested?

kubectl exec -n dynatrace deployment/dynatrace-operator -- dynatrace-operator support-archive --stdout > operator-support-archive.zip

operator-support-archive.zip should be decompressed with no errors.

supportarchive_console.log contains the message :

[support-archive]       envvar content read and set     {"envvar": "modules.json", "value": "{\n  \"csiDriver\": true,\n  \"activeGate\": true,\n  \"oneAgent\": true,\n  \"extensions\": true,\n  \"logMonitoring\": true,\n  \"edgeConnect\": true,\n  \"supportability\": true,\n  \"kspm\": true\n}\n"}
