ce1a58bf58 Provide a more specific error when file doesn't exist

11968faffc Numerous fixes to collective 
If client has higher transaction count, do not close the connection
before extracting peer address.

If our connect session is rudely terminated, abort rather than trying
to continue.

On assimilate failure, ignore a failed assimilate with no data.

Fix problem where a follower getting double deleted was causing an error.

8769c438c0 Relax cryptodomex requirement 
We don't *need* the higher version, it just accelerates password auth
if possible.  Fix conflict with RH provided package.

282043ed97 Switch to cryptodome 
Cryptodome is a modern, but compatible replacement for pycrypto.

We may move to cryptography eventually, but start with this for now
for some nice speedups in some cases.

0b26d12837 Fix memory leaks 
For one, configmanager was left with stale callback references, clean
those up.

For another, the callback pattern was creating a circular reference that
python memory management couldn't overcome.  Break the reference
explicity when an item is disposed of.

97f932b946 Fix the attempt to assimilate 
In the wake of leader loss, the assimilate attempt was causing one
of a couple of bad behaviors, a trace if broken and if it should
work, the format of the data payload was incorrect.

c6a0aeca3b Fix dispatch of commands with InputData

up, to avoid doing pickle load on client input prior to client
validation.

f45228c067 Auto-migrate open console session on loss of management 
This will keep consoles connected across a manager change.  Note
that as it stands, a console session enduring multiple changes will
become increasingly convoluted as the redirect chain will increase
every time, rather than shorting back to the entry point.
