Support filter by tags for pipelines and data storages loading

[ekazachkova]

Background
At the moment, Cloud Pipeline does not allow to load all pipelines/data storages with filter by tags and it would be nice to support it.

Approach
Implements a new methods POST /pipeline/filter for pipelines and POST /datastorage/filter for storages that allow to pass tags filter with the following format:

{
    "tags": {
        "AttributeName1": [ "AttributeValue1", "AttributeValue2" ],
        "AttributeName2": [ "AttributeValue3", "AttributeValue4" ],
        ....
    }
}

In this case a new methods shall load those entities that contains tags (AttributeName1=AttributeValue1 or AttributeName1=AttributeValue2) and (AttributeName2=AttributeValue3 or AttributeName2=AttributeValue4)

If no tags provided all entities shall be loaded.
