[chaos-k8s]Add support to `Delay` in the parser (D.S.L)

[wirednkod]

We should implement it in a way that allow to set all the options: latency, jitter, correlation (this will be mostly 100)

@pepoviola can you elaborate a bit more? Why is there a need to add support of delay on the parser, since it is supported from the toml file?

Yes, because currently we can only set the delay settings as part of the spawning phase. So, ones the network is running you can't modify any of those settings. To allow to add/rm/modify the running network we should support modify the deployed manifest through our D.S.L, so users can for example increase or decrease the latency as part of their test. Make sense? Thanks!
