[plugin] Wildcard group isn't supported in deployment_tasks.yaml

[Sergii Golovatiuk]

There is a case when plugin should be run on some sets of groups. Some groups may be realized by other plugins. Wildcard will eliminate a case when one plugin will require some modification such as

https://github.com/mattymo/detach-database/blob/master/deployment_tasks.yaml#L62-L65

There should be wildcard operators. In this case orchestrator will run plugin on all groups.
the regular expressions (perl format) should be used to specify wildcard.
groups: .* # any group

groups: "^(?!mongo$)" # all groups except mongo

groups: (?=mongo)(?=^((?!^primary).)*$) #all mongo, except primary-mongo

groups: "mongo|astute" # mongo or astute

@Sergii, I've updated the title of the bug to reflect that it affects deployment_tasks.yaml (and not tasks.yaml).

After discussing with @sgolovatiuk, @dshulyak and @akislitsky, @ashtocolov, make design to use regular-expressions (perl format) to describe pattern for group, because
   - it is simple to implement. (python has native support for regular expressions. module "re")
   - any admin or programmer knows the regular expressions.

    Added support of regexp patterns for groups in deployment_tasks.yaml

    Regular expressions (perl format) should be used to specify wildcard.
    '/' used on the end of group name to distinguish regexp from simple string.

    groups: '/.*/' # any group
    groups: '/^(?!controller$)/' # all groups except controller
    groups: '/(?=controller)(?=^((?!^primary).)*$)/' # all controller,
            except primary-controller
    groups: '/mongo|compute/' # mongo or compute
