feat(DX): Add simple __repr__ for DocTypes

refactor: replace inspect.getargspec with getfullargspec

refactor: Send mail functionality

Replace deprecated inspect.getargspec with inspect.getfullargspec.
* inspect.getargspec does not support kw only args aswell as type
annotations.
* replace with inspect.getfullargspec, that supports kw only args.

chore: replace assertEquals with alias assertEqual

`assertEquals` has been deprecated, while not fully removed it will
still keep giving warnings in tests / CI.

ref: https://docs.python.org/3/library/unittest.html#deprecated-aliases

reason: py2 support no longer required and six makes mocking/testing
complicated.

* Don't create task-logs folder during site creation
* Remove old unused async code for tracking tasks

Avoid "DeprecationWarning: invalid escape sequence \W" by using raw
strings instead, If avoided for longer, these lines will throw a
SyntaxError in later Python versions

in get_controller, if cached value doesn't exist for a DocType in the
frappe.db.value_cache, then query the db as fallback before the final
fallback of assuming module as Core and non custom

eg:

Fieldname 'Delete' conflicting with a controller method of the name delete in Custom DocPerm
Fieldname 'Delete' conflicting with a controller method of the name delete in DocPerm
Fieldname 'Precision' conflicting with a controller method of the name precision in Custom Field
Fieldname 'Precision' conflicting with a controller method of the name precision in Customize Form Field
Fieldname 'Precision' conflicting with a controller method of the name precision in DocField

# Conflicts:
#	frappe/core/doctype/doctype/doctype.py

fix: Misc fixes

fix: missing comma and uncommented code in hooks.py template

- Also, reduce lock_interval
