Harden wfs.ts + ogc-client

[esgn]

Problem

Currently some error ar still passing retry. It seems ogc-client emit a HEAD request after a failed GET request.
This triggers a CORS error that is propagated out of retry to the cli.
A fix should be implemented to prevent retry being bypassed by an uncatched error.

GPF-SCHEMA-STORE:RETRY 102220: wfs.getFeatureTypeFull(BDTOPO_V3:canalisation) failed (attempt 1/3), retrying in 209ms
file:///home/ESeguin2/git-clones/github.com/gpf-schema-store/node_modules/dist-node.js:2127
        throw new EndpointError(
              ^

EndpointError: The document could not be fetched due to CORS limitations

Actions

• Create a WfsClient to handle the endpoint from ogc-client
• Move out namespace filtering
• Find a workaround for the ogc-client unhandled errors

ignfab/gpf-schema-store - src/services/wfs.ts - process.on('unhandledRejection',...)

• Report the problem to camptocamp : WfsEndpoint/WmsEndpoint/WmtsEndpoint - the use of promise in constructors lead to unhandledRejection on failure camptocamp/ogc-client#138
• Create PR : Run promise in isReady instead of constructor camptocamp/ogc-client#139 (waiting for merge)

@esgn problem found... The constructor of WfsEndpoint runs a promise -> if it fails, it throws out of the try catch around await isReady()

I'll wrap the full client creation.
