We need to replace the rand.Seed() function with another way since the rand.Seed() function is deprecated, as shown below.
Deprecated: Programs that call Seed and then expect a specific sequence of results from the global random source (using functions such as Int) can be broken when a dependency changes how much it consumes from the global random source. To avoid such breakages, programs that need a specific result sequence should use NewRand(NewSource(seed)) to obtain a random generator that other packages cannot access.
https://pkg.go.dev/math/rand#Seed
However, I don't think we need to set the global random seed to the same value every run since we don't use random values anywhere, as I can see. So, I removed this.
@andreyvelich @johnugeorge WDYT?

I am not sure why did we set these values.
@gaocegege @johnugeorge Do you have any context ?

@andreyvelich As I can see, I can not find any context for this random number by git blame.
It seems that this was copied from https://github.com/mlkube/katib/blob/0bed55aae3cfddf255e6d297e31d1fedbe5dca4a/db/interface.go#L65-L67 to here.
