refactor: pause deployments when overdrawn

[rick-a-lane-ii]

Description

WIP

Refactors the behavior of deployments and deployment groups when accounts are overdrawn. This is an initial update that will likely go through several iterations (within this PR and/or via multiple PRs).

While the current design is impressively clean, there are multiple use cases flowing through common code related to this refactor, and it's likely the design needs to be further updated with either interface changes and/or strategic use of options to improve readability, enhance overall flow control, and separate the functionality of different use cases.

This change is fairly rudimentary so far, but this establishes some sense of the issue at hand. Nor does this address all of the concerns listed in the issue (yet).

Comments welcome early (as always), but this will be progressing through multiple iterative stages, and may completely change shortly.

TODO

• Refactor design (as necessary) to ensure multiple use cases all operate as expected.
• Reconsider appropriate testing design/placement for all changes.
• Add additional automated testing where appropriate.
• Local development environment testing.
• Ensure new lease creation works as stated in conjunction.
• Ensure the escrow balance reflects appropriately.
• Ensure the payment reflects appropriately.

Closes akash-network/support#368
