Fix failure with rbd on slow ceph clusters
Make rados connection interval and retries configurable
for _try_remove_volume() function
Otherwise on slow ceph clusters, we can get following problem:
"ImageBusy error raised while deleting rbd volume. This may have been
caused by a connection from a client that has crashed and, if so,
may be resolved by retrying the delete after 30 seconds has elapsed."
note: Servers must be prepared to deal with multiple
OpenStack-API-Version headers. This could happen when a client
designed to address multiple services always sends the headers it
thinks it needs. Most Python frameworks will handle this by setting
the value of the header to the values of all matching headers,
joined by a ',' (comma). For example ``compute 2.11,identity
2.114``.

Readd iscsi_target table
Rolling upgrades was broken when iscsi_target table was dropped on
https://review.openstack.org/268320
We cannot stop using a table and drop it in the same release for rolling
upgrades to work, we have to stop using it in one release and then drop
it in the next or in the post rolling upgrade mechanism (which is still
not in place).
So this patch fixes this by removing the dropping and adding another
migration that ensure that the table is really there. That way we can
be sure that anyone using M will have the table, which then will get
dropped in N.

Fix issue with Pure drivers delete_snapshot exception handling

Allow for Pure drivers to verify HTTPS requests
This pipes in the config options (driver_ssl_cert_verify and
driver_ssl_cert_path) for verifying https requests to the
purestorage python module. This will allow for the underlying https
management API requests to the array to be verified.
To use this feature a newer (>1.4.0) version of the pure storage python
module will be required.
DocImpact: Need to update Pure Storage Volume Driver config reference
to mention that it can use the new config options and the python module
version requirements that go along with it.
Cinder v2 API allows creating a volume with a quoted (single or double
quotes or even unbalanced number of quotes) display name. But when we
try to get info for such volume, we end up getting an error message
saying that no volume with such a name or ID exists. This error is due
to the inadvertent stripping of quotes from the filter in the api layer.
The api call eventually comes to check_volume_filters() in
cinder/volume/api.py. The invocation of ast.literal_eval() inside this
method strips the quotes for certain quoted strings leading to this
incorrect filtering. ast.literal_eval() is used to convert string
representations into python objects which are then used to frame the
SQL queries in the db layer. For example, the string "[1,2]" for a
filter (not the display name filter) gets converted to a list object
and results in an "IN" operation being emitted in the SQL query as
opposed to an exact match.
When display_name does not contain any quotes or contains an unbalanced
number of quotes, then ast.literal_eval() throws (just like the Python
interpreter would throw for an unquoted string literal or one with
unbalanced number of quotes). We handle this by ignoring the exception
and using the raw input value as the filter and moving on. For string
containing balanced number of quotes, such as, '"foo"',
ast.literal_eval() succeeds and returns the input with the surrounding
quotes stripped (just like how the python interpreter strips quotes
from a string literal to initialize a string var's value in memory).
To always use the raw user input string as the filter value, we can
either not pass string inputs to ast.literal_eval() or encode the
string using encode("string-escape") so that we get the original string
back after passing through ast.literal_eval(). We choose the former as
the latter buys us nothing.

Don't run test_volume.VolumeTestCase twice
Currently the test_volume.VolumeMigrationTestCase class inherits
