Feature Request: Add a `dps.enabled=false` label to containers that shouldn't be resolveable by DPS

[defung]

Summary & Motivation

There are some containers that I don't want exposed to DPS. Would be great if there's a label we can add to those containers to let DPS know to ignore them.

Some potential ideas are:

dps.enabled=false (defaults to true if doesn't exist)
dps.ignore=true (defaults to false if doesn't exist)
dps.disabled=true (defaults to false if doesn't exist)

Example:

docker run -l “dps.enabled=false“ nginx
