This pull request fixes #6402
## Describe Your Solution 🔧
Currently, the group level engine is getting launched with the first user
group itself. This change will allow user to pass in which group they want to
launch the engine.
The flow of implementation is :
- Take input of preferred group
- If it is not defined, take the default route, pick the first group
from the list
- If its defined
- User is not part of preferred group, raise ERROR
- User is part of preferred group,
- If group engine don’t exists, then create a engine with group
name owned by first sessionUser
- If group engine exists, use the existing one
1. In this way, for every group there will be single engine, which can be
re-used.
2. First user launching the engine is implemented to handle the scenarios
where Hadoop groups are not the yarn users.
3. For security concerns in 2nd point, we can have fine grained access
control on session level, using Apache Ranger.

## Test Results🧪
1. When PREFERRED_GROUP was not defined, it used the first group from the
list
Spark application name:
kyuubi_GROUP_SPARK_SQL_Internet_Users_default_d2826b5b-3f1e-48a0-b42f-d248da914b7c

2. When valid PREFERRED_GROUP was defined
Spark application name:

3. When invalid PREFERRED_GROUP was defined
Error: org.apache.kyuubi.KyuubiSQLException: Error operating LaunchEngine:
java.lang.IllegalArgumentException: User is not part of the preferred group:
kyuubi_test_x
4. When any other user X tries to access the existing GROUP engine, it uses
the same engine
