[WIP] Extract Adapters to separate modules, introduce AdapterManager

[patuwwy]

What?

Install Runtime Adapter You will be using, in example:
npm i @scramjet/sth @scramjet/adapter-process @scramjet/adapter-docker

• Runtime Adapters have been moved to dedicated modules.
• Introduced AdapterManager and multiple Runtime Adapters in Host.
• Only specified Runtime Adapters are loaded now and initialized with provided configuration.
• Introduced ability to choose Runtime Adapter when uploading Sequence:
  si seq send <PKG> --runtime-adapter <adapter>
• STH can be started without Runtime Adapters. No /instance, /sequence/ and /sequences endpoints are available in this mode and returns HTTP 404 with meaningful message.

Why?
supplying all adapters is redundant and causes a significant increase in the size of the STH package

Review checks:

These aspects need to be checked by the reviewer:

• Verify and confirm operation (please post a screenshot)
• All STH tests pass
• All Scramjet Cloud Platform tests pass
• Documentation is updated or no changes
