Erlang distribution seems to outperform gen_rpc (unless gen_rpc clients
are scaled up, but this is not easy to achive for shard transport as it
may reorder events).
For some unknown reason, this test has difficulties in syncing the config correctly
between the nodes, while the equivalent in bridge_v2_api_SUITE doesn't.
prior to this commit, dashboard scheam json type conversion
has a 'fallback' type for all unknown types, which is 'string'
this commit removes this fallback and add all possible types
to the function clauses.
also, some of the old types which are no longer in use
are deleted from both swagger spec converter and dashboard
sechema converter
When EMQX boots up, it tries to get latest config from peer (core type)
nodes, if none of the nodes are replying, the node will decide
to boot with local config (and replay the committed changes) if
the commit table is loaded from disk locally (an indication of the
data being latest), otherwise it will sleep for 1-2 seconds and
retry.
This lead to a race condition, e.g. in a two nodes cluster:
1. node1 boots up
2. node2 boots up and copy mnesia table from node1
3. node1 restart before node2 can sync cluster.hocon from it
4. node1 boots up and copy mnesia table from node2
Now that both node1 and node2 has the mnesia `load_node` pointing
to each other (i.e. not a local disk load).
Prior to this fix, the nodes would wait for each other in a dead loop.
This commit fixes the issue by allowing node to boot
with local config if it does not have a lagging.

Several bridges should be able to share a connector pool defined by a
single connector. The connectors should be possible to enable and
disable similar to how one can disable and enable bridges. There should
also be an API for checking the status of a connector and for
add/edit/delete connectors similar to the current bridge API.
