* Revert "fix(test_recorder): get the correct request (#24143)"
This reverts commit 745080c56e.
* test: disable recording before running assertions
* test: Dont set emails in test for broken email setup
Attempt to normalize query by removing "variables"
This gives a different view of similar duplicate queries.
These two are distinct queries:
```sql
select * from user where name = 'x'
select * from user where name = 'z'
```
But their "normalized" form would be same:
```sql
select * from user where name = ?
```
This helps highlight queries ran in loop which might not register as
duplicate but are possibly "duplicate".
By processing `EXPLAIN` of queries in background after recording is
completed, the overhead reduces significantly and hence can be used
"more" in production environment too.
Currently frappe recorder can be enabled globally and profiles every
request. This is often way too much info. If you already know where
problem lies you use this decorator sparingly to only profile relevant
functions.
Usage:
```py
from frappe.recorder import record_queries
@record_queries
def sus_slow_function():
frappe.db.sql("select everything from everywhere")
```

The license.txt file has been replaced with LICENSE for quite a while
now. INAL but it didn't seem accurate to say "hey, checkout license.txt
although there's no such file". Apart from this, there were
inconsistencies in the headers altogether...this change brings
consistency.
* Remove six for PY2 compatability since our dependencies are not, PY2
is legacy.
* Removed usages of utils from future/past libraries since they are
deprecated. This includes 'from __future__ ...' and 'from past...'
statements.
* Removed compatibility imports for PY2, switched from six imports to
standard library imports.
* Removed utils code blocks that handle operations depending on PY2/3
versions.
* Removed 'from __future__ ...' lines from templates/code generators
* Used PY3 syntaxes in place of PY2 compatible blocks. eg: metaclass
