Updated python SDK API

Changes:

1. Added attributes to access to objects (named as object collection):

• Project has:
  • .models, .jobs, .views
• Database has:
  • .tables
• Connection has:
  • .databases, .projects, .ml_engines
  • and all attributes of 'mindsdb' project. It means that connection is also project

Object collections have similar set of attributes

• get
• list
• create
• drop
  Other attributes are interpreted as access to object itself.

Example for tables:

db = con.databases.example_db

# get table
db.tables.get('my_table')

# get the same table as attribute
db.tables.my_table

Old API also works

2. Support of ml_engines (create, view, drop)

3. method to wait till training complete
   model.wait_complete()

4. Support update table (from dict or query)

5. Support insert to table (from query or dataframe)

6. Support delete from table

7. kwargs for modles.create are interpreted as options to model

8. Added examples folder

9. updated documentation, tests

10. Support of ml_handlers and data_handlers (list, get)
