Renaming files with savanna words in its names

* Removed etc/savanna directory:
  - all files are moved to etc/sahara
  - updated etc/sahara/compute.topology and etc/sahara/swift.toppology in configs
* Reanmed savannautils.py in HDP plugin
* Renamed savanna_api.py and savanna_db.py, savanna_subprocess.py
  and updated setup.cfg according that
* Modified alembic README since savanna-db-manage entry point changes

 The migrations in the alembic/versions contain the changes needed to migrate

 a script that details the changes needed to upgrade/downgrade the database. The
 migration scripts are ordered so that multiple scripts can run sequentially to

+which uses the Alembic library to manage the migration. Sahara supports
 migration from Icehouse or later.
 
 
 If you are a deployer or developer and want to migrate from Icehouse to later
 release you must first add version tracking to the database:
 ```
-$ savanna-db-manage --config-file /path/to/savaanna.conf stamp icehouse
+$ sahara-db-manage --config-file /path/to/sahara.conf stamp icehouse
 ```
 
 You can upgrade to the latest database version via:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf upgrade head
+$ sahara-db-manage --config-file /path/to/sahara.conf upgrade head
 ```
 
 To check the current database version:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf current
+$ sahara-db-manage --config-file /path/to/sahara.conf current
 ```
 
 To create a script to run the migration offline:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf upgrade head --sql
+$ sahara-db-manage --config-file /path/to/sahara.conf upgrade head --sql
 ```
 
 To run the offline migration between specific migration versions:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf upgrade \
+$ sahara-db-manage --config-file /path/to/sahara.conf upgrade \
     <start version>:<end version> --sql
 ```
 
 Upgrade the database incrementally:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf upgrade --delta \
+$ sahara-db-manage --config-file /path/to/sahara.conf upgrade --delta \
     <# of revs>
 ```
 
 Downgrade the database by a certain number of revisions:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf downgrade --delta \
+$ sahara-db-manage --config-file /path/to/sahara.conf downgrade --delta \
     <# of revs>
 ```
 
 Create new revision:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf revision \
+$ sahara-db-manage --config-file /path/to/sahara.conf revision \
     -m "description of revision" --autogenerate
 ```
 
 Create a blank file:
 ```
-$ savanna-db-manage --config-file /path/to/savanna.conf revision \
+$ sahara-db-manage --config-file /path/to/sahara.conf revision \
     -m "description of revision"
 ```
 
 To verify that the timeline does branch, you can run this command:
 ```
-    $ savanna-db-manage --config-file /path/to/savanna.conf check_migration
+    $ sahara-db-manage --config-file /path/to/sahara.conf check_migration
 ```
 
 If the migration path does branch, you can find the branch point via:
 ```
-    $ savanna-db-manage --config-file /path/to/savanna.conf history
+    $ sahara-db-manage --config-file /path/to/sahara.conf history
 ```
