This changes Makefile environment variables to be consistent with caravel user project based on feedback from @mattvenn.

Also, the fastest_test_set/extended_test_set productions have been fixed from a break in #627.

* IMAGE_NAME -> OPENLANE_IMAGE_NAME

* CURRENT_TAG -> OPENLANE_TAG

~ PDK build now runs once, result reused
~ Designs run separately
- Removed outdated variables
- Cleanup now should always occur

~ Fixes #620

- #607 - Lack of legalization was causing routing issues with OpenROAD.

- #601 - There is a cryptic "maze ripup wrong" message that makes aes_cipher fail: see The-OpenROAD-Project/OpenROAD#1110

- CU of aes_cipher reduced to 40 (50 was causing issues with TR)

- Fixed or_issue

Detailed placement is already done at this point once in the routing optimization and again if needed in the diode insertion strategy..This if statement just does detailed placement another time which sometimes makes the devices overlap, breaking the flow.

Reading sdc file from post CTS stage. Clocks already propagated so commenting line 46.

Fixes for the multi power domain generation, custom IO placement, and diode insertion strategy 4 (#609)

- Drawing multiple power domains wasn't working properly because `write_powered_def.py` assumed that the default vdd and gnd nets always exist at index 0. This isn't always the case because the nets are ordered differently in the def file. This PR fixes the issue by enforcing the index of the default power and ground net (the default power domain is assumed to be the first net specified by `::env(VDD_NETS)` and `::env(GND_NETS)`). 
- Added two new variables to give more control on the macros connection to the top level power grid.  `FP_PDN_ENABLE_MACROS_GRID` will either enable or disable connecting internal macros to power. 
`FP_PDN_MACRO_HOOKS` gives the ability to specify explicit power connections for internal macros. It is useful when the design has multiple power domains. For example, 
set ::env(FP_PDN_MACRO_HOOKS) "\
	mprj vccd1 vssd1"
will connect macro with instance name `mprj` to the power domain of `vccd1` and `vssd1`. This depends on https://github.com/RTimothyEdwards/open_pdks/pull/161 
- Added @20Mhz's fix for the custom IO placement 
- Updated the `place_diodes.py` to remove the dependency on the `new_int` API which is no longer available in openroad.

Some variables were moved to the PDK. PDK has also been updated.

* `report.sh` was rewritten in python and folded into `report.py`
    * 'E404' reverted- sorry @kareefardi, a lot of code just expects a number.
    * `report.py` was pretty much rewritten, for that matter.
* wns/tns reporting fixed

---

Also significant fixes made with the help of @Manarabdelaty 
* s44 pdn fix: weird substitution issue that somehow only spuriously surfaces
* manual_macro_placement_test pdn fix: FP_PDN_CHECK_NODES set to 0 (Warnings treated as errors by OpenLane, LVS still passes so we are golden)

This reverts commit 46a00b8b.

openroad_app -> 1ea38a76108667badbe79c088472b6162468fcce

- escaped_env_var is not reused correctly so that all escaped characters are correctly escaped

* Rework Multithreading Variables

~ ROUTING_CORES now overridable by environment
- Deprecated TR parameter file removed

* Update default value for ROUTING_CORES

* [BOT] Update openroad_app

openroad_app -> fb8ae93b6c7a5eb0e6fac83360a8a48d76c41885

* Updated `import opendb` to `import odb`

* Update Open_PDKs

This fixes an issue with pip where support for file: was abruptly removed.

This addresses a race condition when a PR is merged when the scheduled CI is running.

Essentially, an image could be pushed with the tag master following a merge, where it would later be rewritten by the CI when it's done with the same master tag.

This makes it so the CI only pushes to a proper named tag and latest.

1. Save state before generating the report. Generating the report reads a run's `config.tcl` which is changed after saving the state, so we should save the state first then generate the report.
2. In `report.sh`, fetching some values happens before generating the values themselve. This adjusts the sequence of commands properly. 
3. Report `E404` instead of `-1` in values that fail to get captured as some of these values can be `-1` themselves.
4. Some indenting in `report.sh`

This adds a step to the CI that uploads log tarballs to the Google Cloud Platform based on a repository secret to help maintainers isolate issues that may only arise in a CI environment.

The relevant repository secret has already been added.

It can easily be extended to support AWS, Azure, etc as it leverages Apache libcloud.

~ Fixed infinite recursion issue with or_issue.py

* escape env variables that have $ in them

* Update open_pdks make target

* Update open_pdks

* [Makefile] Update open_pdks configure arguments

* Override open_pdks default installation path

* Remove /pdk from gen_source target

* Remove more /sky130A/pdk

+ Proper OS detection in installing
+ Version added to installing (version no longer reports as N/A)
~ Fix #553
~ Reordered install steps to be more logical
~ get_tag now usable by other python files

* Update or_resizer_timing.tcl

Using CTS stage generated sdc in resizer timing optimization. Writing sdc file again to use it in routing stage timing check

* Update or_cts.tcl

Write sdc file after CTS to use this during resizer_timing_optimization

* Update or_groute.tcl

Using post cts generated sdc with propagation clock for timing check at routing stage

Fixes  #501

*Actually* fixes #495. Oops.

* Better Reporting

Fixes an odd issue where the design names extracted would be timestamps due to "File not found or empty" being printed and split, creating extra columns.

Also makes the reports explicitly detail if the OpenLane flow has failed outright on a design.

A general cleanup of relevant scripts has been performed.

Fixes #495
