MSDATP: merge Note into find-machines-by-ip.md

Description:

As discussed in issue ticket #5400 (included page "Improve request
performance" title format & placement), I propose to merge the single
Note stub from the file 'improve-request-performance.md' into the file
'find-machines-by-ip.md' and remove the linked include file.

I have also added a few formatting improvements like MD quote indent
marker compatibility spacing as well as replacing tabs with 4 spaces in
the response code block and finally replacing tabs with single spaces
in the Permissions table.

Proposed changes:
- move the MD Note down to directly after the request code block
- replace the include link with the actual file content
- change the MD heading format from H1 title size to H2 section heading
- remove the include source file (redundant after including the Note)
- replace all tabs with 4 spaces, for Github source view compatibility
- reduce 4 spaces to single spaces in the Permissions table
- add MD quote indent marker compatibility spacing to another Note
