* jmap/EmailCreate: add more attributes that were omitted: Headers,
InReplyTo, References, Sender
* add jmap GetEmailSubmissionStatus
* improve email integration tests by adding a thorough test for email
submission
* jmap integration tests: provision principals and domains using the
Stalwart Management API, switching from an in-memory to an internal
directory
* upgrade Stalwart image for devtools/full to 0.14.1
* re-assert which features are implemented or not in 0.14.1
* refactor the integration tests yet again to make it clearer and
easier to see those "features-or-not"
* get rid of old tests that are now better covered by integration tests
* rewrite how we compare expected and actual objects in integration
tests, finally having found a way to ignore the @type attribute
properly instead of having to mutate all objects to remove it
* add endpoints for Mailboxes:
- PATCH mailboxes/{id}
- DELETE mailboxes/{id}
- POST mailboxes
* refactor the pkg/jmap and groupware framework to systematically
return a jmap.State out-of-band of the per-method payloads, since
they are almost always present in JMAP responses, which lead to the
artificial creation of a lot of composed struct types just to also
return the State; on the downside, it adds yet another return
parameter
* made several email related operations multi-account:
QueryEmailSnippets, QueryEmails, QueryEmailsWithSnippets
* add GetIdentitiesForAllAccounts
* add GetEmailsForAllAccounts
* jmap: add CreateIdentity, UpdateIdentity; groupware: add
GetIdentityById, AddIdentity, ModifyIdentity
* add temporary workaround until Calendars, Tasks, Contacts are
implemented in Stalwart when determining the default account for
those: use the mail one in the mean time
* add URL to retrieve all the mailboxes for all the accounts of a user,
as a first use-case for an all-accounts operation, as
/accounts/all/mailboxes
* add URL to retrieve mailbox changes for all the mailboxes of all the
accounts of a user, as a first use-case for an all-accounts
operation, as /accounts/all/mailboxes/changes
* change the defaultAccountId from '*' to '_', as '*' rather indicates
"all" than "default", and we might want to use that for "all
accounts" operations in the future
* refactor(groupware): remove the accountId parameter from the logger()
function, as it is not used anyways, but also confusing for
operations that support multiple account ids
* refactor some pkg/jmap and groupware methods to make more sense from
an API point-of-view
* add path parameter documentation, but automate it by injecting their
definition into the OpenAPI YAML tree that is extracted from the
source code using go-swagger as it is too cumbersome, repetitive and
error-prine to document them in the source code; wrote a TypeScript
file apidoc-process.ts to do so
* add generating an offline HTML file for the OpenAPI documentation
using redocly, and injecting a favicon into the resulting HTML; wrote
a TypeScript file apidoc-postprocess-html.ts to do so
