Update timing signoff methodology (#674)

- Removed the `-min/-max` options from read_liberty since they shouldn't be used for modeling different process corners (<https://github.com/The-OpenROAD-Project/OpenLane/issues/671>).
- Updated the base SDC file to include information about clock uncertainty, clock transition, and timing derate.
- Updated the timing/design optimizations to be done at the typical corner.
- Updated the STA script to generate the SDF file after the routing is concluded.
- Updated the STA script to report more information like clock skew, worst slack, power, area.
- Added some fixes to the report generation to retain the log file index so that we can easily keep track of when the reports are generated.

Docker Overhaul (#673)

This makes a number of internal improvements to the docker build process.

* A common build base

This common build base utilizes the dependency list outlined in `/dependencies` for both yum and pip, with the exception of cu-gr and dr-cu which use an... interesting (read: obtuse) build system. Speaking of...

* A pre-compile dependency list

This allows for the installing of dependencies that may need to be needed to compile *other* dependencies, incl. wheel, pyinstaller, devtoolset, etc.

* Builds now use tarballs

Git is no longer used, saving us the time needed to check out the *entire commit history every single time we build.* To handle submodules, I wrote a special script. Only OpenROAD uses submodules anyhow.

* Rewrote final image

The final image's Dockerfile was a mess. The new one also uses the dependency list and is better organized.

* OpenLane is now mounted to `/openlane` instead of `/openLANE_flow`

We don't really use `openLANE`, branding was settled on `OpenLane`, except I think it's better for everyone's sanity if I avoid capital letters altogether.
