Update log requirement from 0.3.0 to 0.4.13 in /vault-api

[dependabot-preview]

Updates the requirements on log to permit the latest version.

Changelog

Sourced from log's changelog.

[0.4.13] - 2021-01-11

• This is the same as 0.4.11, except with a kv_unstable_std feature added to aid migrating current dependents to 0.4.14 (which was originally going to be 0.4.13 until it was decided to create a patch from 0.4.11 to minimize disruption).

[0.4.12] - 2020-12-24

New

• Support platforms without atomics by racing instead of failing to compile
• Implement Log for Box<T: Log>
• Update cfg-if to 1.0
• Internal reworks of the structured logging API. Removed the Fill API and added source::as_map and source::as_list to easily serialize a Source as either a map of {key: value, ..} or as a list of [(key, value), ..].

Fixed

• Fixed deserialization of LevelFilter to use their u64 index variants

[0.4.11] - 2020-07-09

New

• Support coercing structured values into concrete types.
• Reference the win_dbg_logger in the readme.

Fixed

• Updates a few deprecated items used internally.
• Fixed issues in docs and expands sections.
• Show the correct build badge in the readme.
• Fix up a possible inference breakage with structured value errors.
• Respect formatting flags in structured value formatting.

[0.4.10] - 2019-12-16 (yanked)

Fixed

• Fixed the log! macros so they work in expression context (this regressed in 0.4.9, which has been yanked).

[0.4.9] - 2019-12-12 (yanked)

Minimum Supported Rust Version

This release bumps the minimum compiler version to 1.31.0. This was mainly needed for cfg-if, but between 1.16.0 and 1.31.0 there are a lot of language and library improvements we now take advantage of.
