Lakefs

- Add new "AttachStorageNamespace" IAM action. Controls users' ability to
create repositories with particular storage namespaces (bucket names).
(2220)
- Fix path encoding when checking sigV2 signatures in the S3 gateway.
- [S3 gateway] Return HTTP 409 (Conflict) when creating existing repo (2451)

- Fix double slash bug in storage namespace (2397)

- Add search locations to load lakeFS configuration. More information on
https://docs.lakefs.io/reference/configuration (#2355)
- Fix ARNs parsing confusion when the account-ID field contained a slash or
the resource-ID a colon. Configurations (incorrectly) using a slash "`/`"
to separate account from resource in the ARN will need to switch to use a
colon "`:`". However such configurations are probably incorrect, as
lakeFS does not currently set account fields. And configurations using
resources containing a colon will now work correctly.

- Support multiple AWS regions for underlying buckets (2245, 2325, 2326)
- Make S3 Gateway DNS settings optional
- Fix lakectl upload fails on big uploads (2280)
- Fix blank screen bug in UI (1908)
- Actions secrets support with env vars (2333)
- Reduce the number of database connections used on startup
- Validate required configuration keys blockstore.type, auth.encrypt.secret_key. This breaks existing configurations that assume a default blockstore.type of "local". But no such configuration may be for production.
