feat : support collection type in secondary index

[jadepeng]

支持对cardinality 为list或set 的属性建search和secondary索引
fixed #893

索引定义：

        schema.propertyKey("category").asText().valueSet().create();
        schema.propertyKey("country").asText().create();

        schema.vertexLabel("soft").properties("name", "tags", "country", "category")
              .primaryKeys("name").create();

        schema.indexLabel("softByTag").onV("soft").secondary()
              .by("tags").create();
        schema.indexLabel("softByCategory").onV("soft").search()
              .by("category").create();

        graph.addVertex(T.label, "soft", "name", "hugegraph",
                        "country", "china",
                        "category", Arrays.asList("graphdb", "db"),
                        "tags", Arrays.asList("graphdb", "gremlin"));

        graph.addVertex(T.label, "soft", "name", "neo4j",
                        "country", "usa",
                        "category", Arrays.asList("graphdb", "db"),
                        "tags", Arrays.asList("graphdb", "cypher"));

        graph.addVertex(T.label, "soft", "name", "janusgraph",
                        "country", "usa",
                        "category", Arrays.asList("graphdb", "db"),
                        "tags", Arrays.asList("graphdb", "gremlin"));

查询：

        // query by single item
        vertices = graph.traversal().V().has("soft", "tags", "gremlin").toList();
        Assert.assertEquals(2, vertices.size());

        vertices = graph.traversal().V().has("soft", "tags", "graphdb").toList();
        Assert.assertEquals(3, vertices.size());

        // query by contains
        vertices = graph.traversal().V().has("soft", "tags", ConditionP.contains("gremlin")).toList();
        Assert.assertEquals(2, vertices.size());

@jadepeng Seems CI test fail

u can also run test in local env firstly

[javeme]

can also add some test cases to schema-test?

[javeme]

expect that not allow CONTAINS and TEXT_CONTAINS_ANY for search index, at least not allow TEXT_CONTAINS_ANY

[jadepeng]

TEXT_CONTAINS_ANY 移除，search 不包含CONTAINS ，这个这里判断稍微有点麻烦，是否一定要增加？

[imbajin]

due to travis's ci blocked, the building suspend for 2days, now is fine (ignore mysql/pg)

seems need rebase master to solve conflict

[javeme]

seems ci is failed

[imbajin]

LGTM. Thanks for your contribution again @jadepeng

And due to some reason for code coverage with github ci (I'll try to fix it as soon as possible), this PR may suspend for a while

Update: fix the code coverage problem now.

[imbajin]

@jadepeng could u rebase the master branch into yours to fix the code coverage CI problem? (like another pr)
