This patch adds a new util method to the NsxLib class.
NsxLib will expose a search method to retrieve objects from
backend based on their tags and resource type. Tags argument
must be present in order to search.
Tags are supplied in the following form:
[{'scope': <scope_val>, 'tag': <tag_value>}, ...]
