The GET /os-migrations API take a migration_type and source_compute
filter parameter on the request since the v2.0 API. This adds support
for specifying those parameters in the "nova migration-list" CLI
and related MigrationManager.list() python API binding methods.

A functional test is added which will cover the new options on all
three of the decorated do_migration_list shell methods with lower
bounds on 2.1, 2.59 and 2.66. Since the only type of migration we
can safely generate in a single-node CI job is a resize the test
does a resize. As such, _pick_alternate_flavor is moved into the
base test class for re-use.

The GET /os-migrations API takes both a host and
source_compute filter parameter. The former filters

change clarifies that in the command help for the
--host option.

The 'versioned wrapped shell method' is a bit unclear.
So fix it and add more description for it.
