chore: remove global variable for better unit testing

[namkyu1999]

In Litmus version 2, we already remove global variables. you can see here #3937

However, with the change of Litmus version to 3, we have a new global variable, which we need to change to a field in the struct because global variables make unit testing difficult.

Here's a global variable what we need to remove. https://github.com/litmuschaos/litmus/blob/794676f6b75e08835334fd5d675e0b0d096d5f9d/chaoscenter/graphql/server/pkg/database/mongodb/operations.go#L36

We need to find and change all the places where that global variable is used, like this

Here's an example of what we did first #4136

Anyone who finds good first issues or participates in hacktoberfest can take this issue.
