[mig client] Add option for target agents from results of previous action (Bugzilla #1141910)

[arunk-s]

The link you mentioned in the description is obsolete now ;), maybe you meant this one https://github.com/mozilla/mig/blob/master/client/mig/main.go .
From what I understand is that we need to add two flags: --target-foundanything and --target-foundnothing and they will be evaluated by EvaluateAgentTarget. So does the flags --target-found* hold "Action ID" as their values, such that we are able to build this query

id IN ( \
SELECT agentid FROM commands, json_array_elements(commands.results) AS r \
WHERE commands.actionid = %d AND r#>>'{foundanything}' = 'true')" )

from the input action value and pass it for evaluation ?
Also what preference is given to -t flag in case of use of both -t and --target-found* flags, i.e. should the agents that passes the -t flag should be filtered further on the basis of the -target-found* flags or vice versa ?

Thanks for picking up this issue :)

Yes

Yes

what preference is given to -t flag in case of use of both -t and --target-found* flags

For now, execution should fail and an error should be displayed to the user.
In the future, we could considered merging the two statements together.
