feat: add HTTP and HTTPS to hive

[dpgaspar]

This PR adds support for HTTP and HTTPS protocols with Hive:

SQLAlchemy no Authentication:

from sqlalchemy.engine import create_engine

engine = create_engine("hive+https://localhost:10000/")
rows = engine.connect().execute(
    "SHOW DATABASES"
)
print([row for row in rows])

SQLAlchemy With basic Auth (Hive LDAP authentication for example):

from sqlalchemy.engine import create_engine

engine = create_engine("hive+https://myusername:mypassword@localhost:10000/")
rows = engine.connect().execute(
    "SHOW DATABASES"
)
print([row for row in rows])

SQLAlchemy SSL/TLS check certificate and verify cert hostname:

from sqlalchemy.engine import create_engine


engine = create_engine("hive+https://myusername:mypassword@localhost:10000/?check_hostname=true&ssl_cert=required")
rows = engine.connect().execute(
    "SHOW DATABASES"
)
print([row for row in rows])

SQLAlchemy Kerberos:

from sqlalchemy.engine import create_engine


engine = create_engine("hive+https://localhost:10000/?auth=KERBEROS&kerberos_service_name=krb-service.com")
rows = engine.connect().execute(
    "SHOW DATABASES"
)
print([row for row in rows])

@dpgaspar pyhive is still py2 compatible. Could you please refactor this code to be py2 friendly ?
