Subject: [PATCH] Add supportconfig module for remote calls and SaltSSH

Add log collector for remote purposes

Implement default archive name

Fix imports

Implement runner function

Remove targets data collector function as it is now called by a module instead

Add external method decorator marker

Add utility class for detecting exportable methods

Mark run method as an external function

Implement function setter

Fix imports

Setup config from __opts__

Use utility class

Remove utils class

Allow specify profile from the API parameter directly

Rename module by virtual name

Bypass parent subclass

Implement profiles listing (local only for now)

Specify profile from the state/call

Set default or personalised archive name

Add archives lister

Add personalised name element to the archive name

Use proper args/kwargs to the exported function

Add archives deletion function

Change log level when debugging rendered profiles

Add ability to directly pass profile source when taking local data

Add pillar profile support

Remove extra-line

Fix header

Change output format for deleting archives

Refactor logger output format

Add time/milliseconds to each log notification

Fix imports

Switch output destination by context

Add last archive function

Lintfix

Return consistent type

Change output format for deleted archives report

Implement report archive syncing to the reporting node

Send multiple files at once via rsync, instead of send one after another

Add sync stats formatter

Change signature: cleanup -> move. Update docstring.

Flush empty data from the output format

Report archfiles activity

Refactor imports

Do not remove retcode if it is EX_OK

Do not raise rsync error for undefined archives.

Update header

Add salt-support state module

Move all functions into a callable class object

Support __call__ function in state and command modules as default entrance that does not need to be specified in SLS state syntax

Access from the outside only allowed class methods

Pre-create destination of the archive, preventing single archive copied as a group name

Handle functions exceptions

Add unit test scaffold

Add LogCollector UT for testing regular message

Add LogCollector UT for testing INFO message

Add LogCollector UT for testing WARNING message

Replace hardcoded variables with defined constants

Add LogCollector UT for testing ERROR message

Test title attribute in msg method of LogCollector

Add UT for LogCollector on highlighter method

Add UT for LogCollector on put method

Fix docstrings

Add UT for archive name generator

Add UT for custom archive name

Fix docstring for the UT

Add UT for checking profiles list format

Add Unit Test for existing archives listing

Add UT for the last archive function

Create instance of the support class

Add UT for successfully deleting all archives

Add UT for deleting archives with failures

Add UI for formatting sync stats and order preservation

Add UT for testing sync failure when no archives has been specified

Add UT for last picked archive has not found

Add UT for last specified archive was not found

Bugfix: do not create an array with None element in it

Fix UT for found bugfix

Add UT for syncing no archives failure

Add UT for sync function

Add UT for run support function

Fix docstring for function "run"

lintfix: use 'salt.support.mock' and 'patch()'

Rewrite subdirectory creation and do not rely on Python3-only code

Lintfix: remove unused imports

Lintfix: regexp strings

Break-down oneliner if/else clause

Use ordered dictionary to preserve order of the state.

This has transparent effect to the current process: OrderedDict is the
same as just Python dict, except it is preserving order of the state
chunks.

Refactor state processing class.

Add __call__ function to process single-id syntax

Add backward-compatibility with default SLS syntax (id-per-call)

Lintfix: E1120 no value in argument 'name' for class constructor

Remove unused import

Check last function by full name
