Implement missing Runtime Configurations and Values

[jonathan-mayer]

Issue

Some Configurations aren't implemented yet:

• [x] --matching-labels cli argument (not in code at al)
• [x] grace period
• [x] time annotation
• [ ] dry-run
• [x] exclude namespaces
• [x] exclude workloads

Also currently the Time Annotation is an layer value. This needs to be changed, as it is only supposed to be set via the cli arguments and doesn't need to be in the Layer struct.

Problem to solve

Implement the cli arguments and values. Remove the time annotation value from the layer struct and make a variable in main that holds the runtime configuration value.

Further details

once #27 is implemented, the matching labels could be implemented by iterating over the annotations and checking via the new function using fmt.Sprintf("%s=%s", annotation, value)

Proposal

still have to do: dry-run exclude namespaces exclude workloads

and test the matching-labels

[jonathan-mayer]

to implement dry run i probably have to wait for #31 to merge

[jonathan-mayer]

dry run should also stop error events from being applied to the workload
