pgAdmin4 launch issue on Windows.
Cryptography's new version may be creating a problem. This is a temporary
fix and will have to investigate the proper fix.
1) Upgraded passlib==1.7.1 to passlib==1.7.2
2) Replace unmaintained Flask-Security with maintained Flask-Security-Too package, which is also compatible with python 3.8
3) Other compatibility code changes.
Changes include:
1) Remove underscore-string and sprintf-js packages as we were using only %s. Instead, added a function to do the same. Also changed gettext to behave like sprintf directly.
2) backgrid.sizeable.columns was not used anywhere, removed. @babel/polyfill is deprecated, replaced it with core-js.
3) Moved few css to make sure they get minified and bundled.
4) Added Flask-Compress to send static files as compressed gzip. This will reduce network traffic and improve initial load time for pgAdmin.
5) Split few JS files to make code reusable.
6) Lazy load few modules like leaflet, wkx is required only if geometry viewer is opened. snapsvg loaded only when explain plan is executed. This will improve sqleditor initial opening time.

Also, do not fetch the scenario-name, when it is not avaiable (but - use
default vaule as the stringified test-case itself).
Right now psycopg2 is required to be exactly version 2.6.2, which makes it mostly impossible to install pgadmin4 without having the postgresql C development packages installed (since you need to rebuild psycopg2 from source to make that work, given that few platforms ship *exactly* that version).
1) To handle non-ascii filenames which we set from table name. Fixes#2314
2) To handle non-ascii query data. Fixes#2253
3) To dump JSON type columns properly in csv. Fixes#2360
server connection.
The BaseDriver and BaseConnection are two abstract classes, which allows
us to replace the existing driver with the currently used. The current
implementation supports to connect the PostgreSQL and Postgres Plus
Advanced Server using the psycopg2 driver.
