Issue:
required a support adding new flag which will wait before trigger next suite
Hi
I am using pabot for robot parallel execution and I have a requirement of executing the suites in parallel but need to some time to between each suite. For example, I have suite1 and suite2 and I need to trigger them with some delay as below

Suite1 and wait $DELAY and Suite2

Could you please look at this and implement? it will be helpful for others also

Hints from issue comments:
@joonaskuisma: Hi @kbogineni !  

The `#SLEEP` keyword has been implemented and is just waiting for review and merging into the main branch. If you get a chance, please take a look at #621.  

Any feedback is highly appreciated! 😊  
@kbogineni: @joonaskuisma how the pabot command looks if this is fixed@joonaskuisma: Here is section of updated README.md (You can find it my fork and feature branch also):

By using the command #SLEEP X, where X is an integer in the range [0-3600] (in seconds), you can define a startup delay for each subprocess. #SLEEP affects the next line unless the next line starts a group with {, in which case the delay applies to the entire group. If the next line begins with --test or --suite, the delay is applied to that specific item. Any other occurrences of #SLEEP are ignored.

The following example clarifies the behavior:

`pabot --process 2 --ordering order.txt data_1`

where order.txt is:

````
#SLEEP 1
{
#SLEEP 2
--suite Data 1.suite A
#SLEEP 3
--suite Data 1.suite B
#SLEEP 4
}
#SLEEP 5
#SLEEP 6
--suite Data 1.suite C
#SLEEP 7
--suite Data 1.suite D
#SLEEP 8
```` 

prints something like this:

```````

What you think about this solution? (See my previous comment)@kbogineni: It looks good to me but is there any other solution to add it as command line arguments@mkorpela: Done in 4.2.0
